Time goes on, days change. Riska and her best friend Zia are famous as one of the smart kids in her school. There are no Riska and Zia grades below the grade average, all above the grade average. The two of them not only confided in each other but also exchanged knowledge, be it religious science or science. If Zia does not understand the subject matter that has been given, then Zia will definitely ask Riska and vice versa if Riska who does not understand the content of the subject matter, then Zia will definitely ask Riska, and Riska will ask Zia. Not even hesitating classmates also asked Zia or Riska to explain back the subject matter that the teacher had given and with pleasure Riska and Zia explained to friends in his class.
Sharing knowledge shows that we have something more than others, and we deserve to share it with others. It will add our gratitude to God. When we can share knowledge there is gratitude in the heart, it turns out we can give knowledge that we milki to others. And there is the virtue of teaching knowledge that is beneficial to others, so for him the reward is equal to the reward of those who benefit from it, and the reward continues unbroken to everyone who learns this science from its path.
Riska's favorite subjects are English, Math, and IPA. While Zia's favorite subjects are Religious Education, Mathematics and PPKn. Even the two of them were never absent to raise their hands when the teacher asked a question about the lesson being taught, because it always raises his hand when the question so that the teacher who gave the subject has memorized definitely Riska or Zia can answer the questions given. Until there was one event during the math lesson, a math teacher named Ms. Rosdiana or commonly known as Ms. Ros, gave a problem on the board written about the roots and logarithms, and, then ask the students in the class who can answer the question. Again, the one who raised his hand was Riska and Zia, but then Mother Ros then did not ask Riska or Zia to come forward, to the front, because Ros's mother knew that the two of them could definitely answer the given question. Finally, Ms. Ros took the initiative to point directly from the absence of who should go forward, this is where the classroom atmosphere became tense, a rowdy voice immediately sounded, students such as those who protest why should be appointed from the list of absences, why not Riska or Zia who was appointed to come forward. But what is okay for them to accept fate, because Mother Ros is bored always Riska or Zia who advances forward.
"Assalamu'alaikum" said Mother Ros.
"Waalaikumsalam" replied the students in the same class.
"Today before going into the new material, I want to test the material that last week was about the roots and logarithms" Mother Ros said, then Mother Ros wrote the problem on the board.
"Determine value from: 2log 8 + 3log 9 + 5log 125 "
"Determine value of √2log 8 "
"Mother reminds us that Root in mathematics is one of the algebraic operations whose value is the result of multiplication of the same number or other form to denote a number of rank. The root form is a number whose result is not a rational or irrational number"
" The logarithm is an inverse or inverse of the expiry (exponent) used to determine the magnitude of a principal number" Mother Ros said. The students in the class only nodded their heads as Mother Ros was explaining the root matter and logarithm, whether they actually understood it or not.
There will be two designated students. The students in the class also recorded the questions given, and they thought surely as usual Riska and Zia who could answer the questions, so they survived. Riska and Zia also recorded the questions given by Ms. Ros and immediately answered the questions in the book.
"Who has finished answering the problem, please come forward" said Ms. Ros.
"I am ma'am" Riska and Zia replied simultaneously.
"Who else but Riska and Zia? " Ask Mother Ros.
"For two things this time I'm sorry I won't ask Riska or Zia ahead yes, because I believe Riska and Zia can certainly do it. If no one raises their hand again, then Mother will point from the list of absences yes" said Ms. Ros.
The class suddenly became violent.
"Yaaaah, that's what ma'am is"
"That's what dong bu is, just the name"
"Yaaaah ma'am, argue where no more matter"
Some kind of protest made by the students in the class.
"It's quiet later if you can't guide later so you can "Say Mother Ros while developing her smile, said Ros, because Mother Ros actually wanted to laugh seeing the faces of her students who looked tense with various kinds of expressions, someone immediately dropped her head onto the table so as not to be seen, he said, someone moves his hands and someone holds his forehead to look like a dizzy person. Finally Mother Ros saw the list of absences and called two names of students to be asked to come forward.
"Mom wants Audrey Mariska and Raihan Hanan to come forward" Ms Ros said.
Those who have that name will not want to be full of compulsion, though, even Audrey came forward while her face was bent because her name was upset and Raihan from earlier was just busy scratching her head that was not upset because the tangent had to write the answer on the board. They both have recorded two problems given, but not a single problem has been answered because they do not understand. Finally, with patience, Mother Ros guided them, reminded them of the formula and asked them to calculate the results themselves, and it worked. Audrey and Raihan solve a math problem, both of them smile, and unconsciously say the word "yesss" while their hands are clenched.
Then Audrey and Raihan were asked to return to their respective benches.
Even the intelligence possessed by Riska and Zia has been heard to the Headmaster and his ranks, so Riska and Zia have been prepared by the school to participate in the Mathematics Olympiad. The International Mathematical Olympiad (IMO) is an annual mathematics competition for high school students. It is the oldest international science olympiad. Following the prevalence of IMO (International Mathematical Olympiad), the scope of OSN mathematical materials is divided into four groups: algebra, geometry, combinatorics, and number theory.
The news that Riska has been included in the Olympic math team has been heard in Reza's ears, and this adds to the list of values Reza admiration for Riska, namely beautiful, friendly, sholehah, and, simple and intelligent. Reza also when sitting in the 1st grade of High School was selected to be a participant of the Mathematics Olympiad, therefore Reza was asked by the school to be involved in accompanying his classmates who will participate in this competition. Of course Reza gladly accepted the task, because thus Reza could meet with Riska continuously during the training period. Reza will provide his experience, namely in the form of learning how to deal with the Effective Olympic Race, namely studying the material in depth, doing practice questions, learning problem-solving strategies, taking Olympic race training, and learning how to solve problems, make a regular study plan, and maintain health. This certainly makes Tasya sultry, seeing the closeness of Reza with Riska, but never once Reza was together with Riska, there must always be someone who accompanied Riska, who else if not his best friend is Zia. Actually Reza was a little disappointed, because every time Reza would accompany the training matter for Riska at Riska school was never alone, even if Zia did not exist there must be a teacher who accompanied, he said, because Riska had expressed her objection to the race preparation committee if Riska did not want to while training about just alone with the non-mahrom. This was also done by the committee. But although a little disappointed, Reza remained grateful for being able to be near Riska.
Tasya saw the closeness of Reza with Riska who was in the activities of the mading group alone was like a man of rage, moreover, Reza is involved to provide motivation and training questions to the participants of the race, one of which is Riska. Tasya is increasingly aggressive to disturb Riska, and unknowingly Tasya is increasingly possessive of Reza. This makes Reza actually more disappointed with Tasya's attitude which he thinks is excessive.
Tasya is increasingly keen to harass Riska, whose goal is none other than to keep Riska away from Reza. Though Riska also touched on when Riska tried to approach Reza, there were also those who always met indeed because of conditions that required them to meet.
Once, when he was in school, Riska was buying iced tea, when he was going to bring the iced tea, Tasya pretended his hand was holding the iced tea that Riska was holding, as a result, the iced tea slightly makes the tip of the Riska hijab wet because it spills. Not to mention when Riska was performing dhuhur prayers at school musholla, Tasya berjahili Riska by taking and storing the right side of his shoes Riska in a pot of plants near the bathroom, and the rest of the house, thankfully the shoes to his right Riska can be found again, because there is one of the students who saw Tasya while doing the action, so when Riska was busy looking for his shoes, he said, the student tells Riska that her shoes are in a pot of plants near the bathroom. Riska felt grateful, there were still good people who wanted to help her. But Riska is still patient. Actually, Zia was tired of seeing Tasya's behavior towards Riska, but again Riska always said 'PATTERN', then Riska reminded Zia why we have to be patient, but again Riska always said 'BABAR', then Riska reminded Zia why we have to be patient, because patience and gratitude are two commendable traits that must be owned by a Muslim. Both are proofs of faith in Allah SWT, who created all things with His wisdom and mercy. Patience and gratitude are also the keys to gaining happiness and success in the world and the hereafter. One example of patience is holding back when angry. When Riska had issued a soothing advice, as usual Zia immediately issued a protest of her origin,
"Patience... Patience... Patient people wide body" said Zia origin while sneering her lips.
Riska just smiled at her friend's behavior. But Riska's patience never reached the end, which is when Tasya cast scribbles mading decoration decoration that Riska and his friends have made. It's hard Riska and her friends in the mading decorating mading to make it look interesting to read, Suddenly Tasya came with a marker in her hand and without permission immediately scribbled the adorned. Of course this makes Riska and her friends angry, then Riska also reprimanded Tasya.
"Ka Tasya why you should paint a doodle decor mading, this is our result of hard work" said Riska still with polite language.
"Jelek tau decor, udik that is not interesting, where it is nice to see, mending I add decoration so good right now" Tasya replied while casually continuing to draw on the cardboard where the mading will be affixed.
"Ka Tasya stop, later I will report to the school like this" Riska said.
"Report me, before the school rebukes me, you will also first get you out of this school, tauuuu... " Tasya Threatened.
"Will you threaten me? Oooh all right, Kaka forgot who Papa I am? I can get Ka Tasya out of this school right now, even I can also ask my papa to make Ka Tasya not accepted in any school" Riska said sharply. Riska was forced to say so, because to create a deterrent effect on Tasya. Though all this time Riska never want to bring the big name of her father. Riska friends also know Riska because of cleverness, friendliness, simplicity and of course the beauty that Riska has, only this time Riska's friends in the mading know who Riska really is and they are amazed to never see the slightest Riska being arrogant or showing off. Zia also smiled with satisfaction to see Riska and Tasya's quarrel this time, let alone see Tasya's face that was immediately pale when she heard Riska's threat.
"Sukurinnnn know the taste" Zia said in her heart with a satisfied smile.
" Jlegerrrrr... "
Like lightning in broad daylight hearing Riska's words earlier, Tasya cursed himself, Tasya forgot that Papa Riska was one of the famous people, who certainly could do anything if it was desired.
"I'm so stupid, I forgot who Riska's father was" Tasya spoke to himself as his face looked pale. Finally Tasya could not say anything more, because it had been checked by Riska, because of shame Tasya went to leave Riska with his legs stopped, indicating that Tasya was very angry.
But still, this does not discourage Tasya to always disturb Riska. As long as Riska is near Reza, Tasya will always raise the war flag against Riska. Zia was worried about this, but again Riska calmed her down.
"Relax Zi, there is God"
"anything we do is not wrong"
"Remember Zi, Islam teaches not to interfere in the affairs of others, especially until we harass and hurt them. This is a waste of time and is not useful. It only ends in sin. Intervening in the affairs of others in this context is an intervention that triggers liver disease or causes sin" said Riska who sounded very cool in Zia's ear. Zia then hugged her best friend, Zia was always proud of Riska who could act mature beyond her age.
