The duas the Quran and Sunnah give for seeking knowledge, sitting an exam, and asking for a difficult thing to be made easy — with meanings, sources, and an honest word about what dua is for.

The central dua for knowledge is Quranic and three words long: Rabbi zidni ’ilma — “My Lord, increase me in knowledge” (Quran 20:114). For something that feels impossible, the narrated dua is Allahumma la sahla illa ma ja’altahu sahlan. There is no authentic dua that replaces studying: the Prophet صلى الله عليه وسلم instructed a man to tie his camel and trust in Allah.
Key takeaways
The central dua for knowledge is Quranic and three words long: Rabbi zidni 'ilma — "My Lord, increase me in knowledge" (Quran 20:114).
For something that feels impossible there is a specific dua: Allahumma la sahla illa ma ja'altahu sahlan — "O Allah, nothing is easy except what You make easy."
Dua is asked alongside preparation, never instead of it. "Tie your camel, then trust in Allah" is the principle, and it is a narration, not a proverb.
There is no narrated dua that produces memorisation without work — and any page promising one is selling something.
Memory in the Islamic tradition is trained the way a muscle is: little, daily, and reviewed.
Searches for a dua before an exam spike twice a year, and there is nothing wrong with that — turning to Allah at a moment of pressure is exactly what dua is for. But the Sunnah frames it in a way worth stating up front, because it changes how the duas below are meant to be used.
When a man left his camel untied and said he was trusting in Allah, the Prophet صلى الله عليه وسلم told him to tie it and trust in Allah. Dua is the second half of that sentence, never a replacement for the first. A student who has revised and makes dua is doing what was taught. A student who has not revised and makes dua is asking Allah for someone else's outcome.
Our Lord, accept from us. Indeed You are the All-Hearing, the All-Knowing.

About the sources on this page
Every dua below is given with the collection it comes from — Sahih al-Bukhari, Sahih Muslim, Abu Dawud, Tirmidhi, Ibn Majah — or, where it is from the Quran, with its exact surah and verse. We cite collections rather than hadith numbers on purpose: numbering differs between printings, and a wrong number helps nobody. If you want to trace a narration to its exact place, ask your teacher or an imam you trust, and check it in a printed collection you have to hand. This page is a learning aid for families, not a substitute for a scholar.
Is there a dua to improve memory?
This is the question behind most searches that land here, so it deserves a straight answer. There are narrated duas asking Allah for beneficial knowledge and for ease in difficulty — several are above, and they are sound. There is no narrated dua that installs information in the mind without study, and the reports that circulate promising exactly that are, at best, unverifiable.
What the tradition does offer on memory is method, and it is strikingly consistent with what modern research on retention found much later: short daily sessions rather than long occasional ones, immediate review of what was just learned, and regular revisiting of old material so it does not decay. The scholars of hifz have taught it that way for centuries. We wrote about the mechanics of it in how to memorize the Quran and, for parents, in helping your child memorise.
The dua of Musa عليه السلام, and why it fits an exam so well
The second dua in the list above is the one Musa عليه السلام made when he was sent to Pharaoh — a task he found genuinely frightening. He asked for four things: an expanded chest, an eased task, a loosened tongue, and to be understood. Read it again with an examination hall in mind and the fit is obvious: composure, ease, the ability to articulate, and to be understood by whoever is marking.
It is a good example of why learning the meanings matters. Said as sounds, it is a formula. Understood, it is precisely the thing you wanted to ask for.
A practical order for a student
Before studying:Rabbi zidni 'ilma, and the dua for beneficial knowledge.
When stuck on something hard:Allahumma la sahla illa ma ja'altahu sahlan.
Leaving for the exam: the dua for leaving the house.
Before the paper is turned over: the dua of Musa عليه السلام.
Afterwards:Rabbana taqabbal minna — and then leave the result with Allah.
That last step is the one students skip, and it is the one that protects them. Dua does not guarantee a particular grade; it puts the outcome in the hands of the One who decides it. A student who has revised, prayed and handed the paper in has done everything asked of them.
Memorisation is a skill, and it can be taught
One-to-one Quran memorisation classes with a teacher who sets your daily portion and holds you to the review schedule. First class free.
There is no single narrated 'exam dua'. The ones used are Rabbi zidni 'ilma (Quran 20:114) for knowledge, the dua of Musa عليه السلام (Quran 20:25-28) for composure and clear speech, and Allahumma la sahla illa ma ja'altahu sahlan for difficulty.
What is the dua before studying?
Rabbi zidni 'ilma — "My Lord, increase me in knowledge", from Quran 20:114. Many students add Allahumma inni as'aluka 'ilman nafi'an, asking for knowledge that benefits.
Is there a dua to improve memory?
There are narrated duas asking Allah for beneficial knowledge and for ease, and they are sound. There is no authentic dua that replaces study. Reports promising memorisation without effort are unverifiable and should be treated with caution.
What does Rabbi zidni ilma mean?
"My Lord, increase me in knowledge." It is from Quran 20:114, and it is the only place in the Quran where Allah instructs the Prophet ﷺ to ask for an increase in something.
Can I make dua in English before an exam?
Yes. Dua may be made in any language. The narrated wordings are in Arabic and carry the merit of the exact phrasing, but Allah understands whatever you ask in.
Does making dua mean I do not need to revise?
No. The Prophet ﷺ instructed a man to tie his camel and trust in Allah. Dua accompanies preparation; it does not substitute for it.
