Rabbi zidni ‘ilma.
My Lord, increase me in knowledge.
Rabbi-shrah li sadri. Wa yassir li amri. Wahlul ‘uqdatan min lisani. Yafqahu qawli.
My Lord, open my heart, make my task easier, and loosen the impediment in my speech so that they understand what I say.
What the selected prayers ask for
Quran 20:114 contains a request for increased knowledge. Musa’s prayer in 20:25–28 asks for openness, ease and speech that others can understand. Together, these address learning and communicating rather than guessing questions or guaranteeing marks.
The first verse occurs in instruction concerning revelation; the second belongs to Musa’s mission. Their use by a student is a general application of their meanings. Neither passage mentions an examination, a timetable or a required number of repetitions.
Before, during and after a test
Before the test, read a meaning you understand and identify what you need help with. Pair the prayer with revision, adequate rest and checking the examination instructions. Those are practical preparation steps, rather than a religiously prescribed sequence.
During the test, work within its rules. Afterward, ask for a beneficial outcome and reflect on what you can improve. A difficult result does not establish that your dua was rejected or that you failed to recite enough.
Learning the wording
Start with one short prayer. Read its Arabic alongside the transliteration, then have your pronunciation checked by someone competent in Arabic. Transliteration is a learning aid and cannot represent every Arabic sound.
Keep the Quranic wording separate from your own request about a particular subject or test. You do not need to turn an ordinary revision plan into a fixed devotional formula.
Common questions
Is there a special dua that guarantees passing? These sources do not establish one. Must I say it a set number of times? No examination count is given here. What if I forget the Arabic? Understanding the request still helps you make a personal supplication; questions about language inside salah belong to a separate prayer lesson.
