Rabbi Zidni ‘Ilma (رَبِّ زِدْنِي عِلْمًا) is a three-word du‘a from the Quran that means “My Lord, increase me in knowledge.” It is one of only a handful of supplications that Allah Himself commanded the Prophet Muhammad ﷺ to recite — making it among the most spiritually weighty short du‘as in the Quran.
This guide covers the full Arabic, transliteration, English meaning, the Quranic context (Surah Ta-Ha 20:114), the longer cultural variant “Rabbi Zidni ‘Ilma Warzuqni Fahma,” the most complete Prophetic dua for knowledge from Sahih Muslim, when to recite, and FAQ.

Rabbi Zidni Ilma Meaning
Three Arabic words, layered with meaning:
- Rabbi (رَبِّ) — “My Lord,” a deeply personal address (not just “Allah” or “Lord” in general). The word Rabb carries the sense of one who nurtures, teaches, and brings to maturity.
- Zidni (زِدْنِي) — “Increase me.” Imperative form — a request, not a question. The Arabic implies adding to an existing amount, not starting from zero.
- ‘Ilma (عِلْمًا) — “in knowledge.” The Arabic ‘ilm covers both religious knowledge (knowledge of Allah, the deen, the Quran) and beneficial worldly knowledge.
Together: “My Lord, increase me in knowledge.” A continuous request — you ask not because you have no knowledge, but because no matter how much you have, more is always better.
Rabbi Zidni Ilma in Arabic
رَبِّ زِدْنِي عِلْمًا
Transliteration: Rabbi zidni ‘ilma.
Translation: “My Lord, increase me in knowledge.”
The Quranic Source: Surah Ta-Ha 20:114
The dua appears in the verse immediately preceding the story of Adam and the angels in Surah Ta-Ha. Allah says to the Prophet Muhammad ﷺ:
“So high above all is Allah, the True King. And do not hasten with the Quran before its revelation is completed to you, and say: Rabbi zidni ‘ilma — My Lord, increase me in knowledge.”
[Surah Ta-Ha 20:114]
The context is striking. Allah is teaching the Prophet ﷺ — the most knowledgeable human, the recipient of revelation itself — to ask for more knowledge. If the Prophet ﷺ was commanded to make this du‘a, every Muslim after him should make it too.
Tafsir: Why “Knowledge” Specifically?
Imam Ibn Kathir notes that of all the things a Muslim could ask for — wealth, status, health, safety — Allah singled out knowledge in this verse. The reasoning across classical tafsir converges on three points:
Related:
- Knowledge is the foundation of every other good. You cannot worship Allah correctly without knowledge of Him. You cannot make halal income without knowledge of what is halal. You cannot raise righteous children without knowledge of how to.
- Knowledge is the only thing the Prophet ﷺ was commanded to seek more of. No similar verse asks Allah to increase the Prophet’s ﷺ wealth, sustenance, or status. Just knowledge.
- Knowledge is the inheritance of the Prophets. The Prophet ﷺ said: “The scholars are the heirs of the Prophets — the Prophets did not leave behind dinars or dirhams; they left behind knowledge. Whoever takes it has taken an abundant share.” (Sunan Abi Dawud 3641, sahih)
The Longer Variant: “Rabbi Zidni ‘Ilma Warzuqni Fahma”
رَبِّ زِدْنِي عِلْمًا وَارْزُقْنِي فَهْمًا
Rabbi zidni ‘ilma, warzuqni fahma.
Meaning: “My Lord, increase me in knowledge, and grant me understanding.”
This longer form circulates widely on social media and in some prayer collections. The first half is Quranic; the second half is not. “Warzuqni fahma” (grant me understanding) is a culturally-added supplement, not in the verse and not a hadith phrase from the Prophet ﷺ in this exact wording.
It is permissible to add it as your own du‘a — the meaning is sound and the addition is sincere. But the cleanest practice is to recite the Quranic form (“Rabbi zidni ‘ilma” alone) when seeking the specific reward of the verse, and use the longer form as a personal du‘a beyond it.
The Most Complete Prophetic Dua for Knowledge
The Prophet Muhammad ﷺ taught a fuller du‘a for knowledge. Reciting both is the strongest sunnah:
اللَّهُمَّ إِنِّي أَسْأَلُكَ عِلْمًا نَافِعًا، وَرِزْقًا طَيِّبًا، وَعَمَلًا مُتَقَبَّلًا
Allahumma inni as’aluka ‘ilman nafi‘an, wa rizqan tayyiban, wa ‘amalan mutaqabbalan.
Meaning: “O Allah, I ask You for beneficial knowledge, wholesome sustenance, and accepted deeds.” (Sunan Ibn Majah 925, sahih)
And the Prophet’s ﷺ counterpart du‘a, seeking refuge from the wrong kind:
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لَا يَنْفَعُ
Allahumma inni a‘udhu bika min ‘ilmin la yanfa‘.
Meaning: “O Allah, I seek refuge in You from knowledge that does not benefit.” (Sahih Muslim 2722) The Prophet ﷺ feared not just ignorance but useless knowledge — the kind that puffs up the self without softening the heart.
When to Recite Rabbi Zidni Ilma
- Before any session of study — opening a textbook, attending a lecture, sitting down to memorize Quran, before an exam.
- Before reciting the Quran — especially as the verse comes from a context of receiving revelation. Reciting it before tilawah opens the heart for understanding.
- In sujood — the closest position to Allah, where du‘as are most likely to be answered (Sahih Muslim 482).
- Last third of the night — when Allah descends to the lowest heaven (Sahih al-Bukhari 1145).
- In the morning adhkar — pair with the Prophetic dua “Allahumma inni as’aluka ‘ilman nafi‘an” for a complete daily knowledge-seeking du‘a.
- When facing a problem you don’t know how to solve — sometimes the answer is more knowledge of the situation, the people, or yourself.
Benefits of Reciting Rabbi Zidni Ilma
- Quranic wording — the safest form of du‘a. Allah Himself chose these three words; nothing you could say is better.
- Three words — impossible to forget. Children memorize it in minutes. Easier than any other knowledge du‘a in the Quran.
- Aligns the heart with the Sunnah of the Prophet ﷺ. The man with the most knowledge in human history asked for more — following his example is honoring his Sunnah.
- Knowledge is barakah (blessing) made tangible. The Prophet ﷺ said: “Whoever Allah wills good for, He gives him understanding of the deen.” (Sahih al-Bukhari 71)
- It applies to every kind of knowledge. Studying medicine, computer science, accounting, or fiqh — the same du‘a opens the door for understanding any beneficial subject.
Frequently Asked Questions
What does Rabbi Zidni Ilma mean?
Rabbi Zidni ‘Ilma (رَبِّ زِدْنِي عِلْمًا) means “My Lord, increase me in knowledge.” It is a Quranic du‘a from Surah Ta-Ha 20:114, in which Allah commands the Prophet Muhammad ﷺ to recite this short, three-word supplication asking for more knowledge.
Is Rabbi Zidni Ilma in the Quran?
Yes. It appears in Surah Ta-Ha, verse 20:114. The full verse reads: “So high above all is Allah, the True King. And do not hasten with the Quran before its revelation is completed to you, and say: Rabbi zidni ‘ilma.” This is one of only a few du‘as Allah Himself commanded the Prophet ﷺ to recite verbatim.
Is the longer version ‘Rabbi Zidni Ilma Warzuqni Fahma’ in the Quran?
No. The first half — “Rabbi zidni ‘ilma” — is Quranic. The second half — “warzuqni fahma” (grant me understanding) — is a culturally-added supplement, not in the verse and not a hadith phrase. It is permissible to add it as your own du‘a, but for the specific reward of the verse, recite only the Quranic form.
When is the best time to recite Rabbi Zidni Ilma?
Best times: before any session of study (lecture, textbook, exam, Quran memorization), before reciting the Quran, in sujood of every salah, in the last third of the night, and as part of the morning adhkar. The du‘a fits naturally before any moment when you are about to take in new information.
What other duas for knowledge did the Prophet ﷺ teach?
The most complete is from Sunan Ibn Majah 925: “Allahumma inni as’aluka ‘ilman nafi‘an, wa rizqan tayyiban, wa ‘amalan mutaqabbalan” — “O Allah, I ask You for beneficial knowledge, wholesome sustenance, and accepted deeds.” And from Sahih Muslim 2722, the Prophet ﷺ also sought refuge from useless knowledge: “Allahumma inni a‘udhu bika min ‘ilmin la yanfa‘.”
Does this dua apply only to religious knowledge?
No. The Arabic word ‘ilm covers all forms of beneficial knowledge — knowledge of the deen, the Quran, the world, the sciences, and one’s own profession. As long as the knowledge is beneficial (nafi‘), it falls under this du‘a. Students of medicine, engineering, fiqh, and any other discipline can recite it before study.
