The Virtue of Saying 'I Don't Know'

The Scholarly Tradition

Imam Malik ibn Anas, one of the four imams of Islamic jurisprudence, whose Muwatta is among the earliest and most authoritative collections of hadith and legal rulings, was asked a question by a man who had travelled from a distant country to consult him. Malik replied: "I don't know."

The man was astonished. He said: "But the people of my country sent me to you specifically."

Malik said: "Then return to your people and tell them that Malik says: 'I don't know.'"

This story is not an exception. It is a pattern across the greatest Islamic scholars. Ibn Masud said: "Whoever has knowledge of everything has been afflicted with the greatest trial." Al-Shafi'i said: "Whenever I debated a man of knowledge and he said 'I don't know,' I knew I was speaking to a scholar." Ahmad ibn Hanbal, asked questions he could not answer with certainty, would say: "I don't know" routinely, in front of students who had travelled great distances to hear him.

The willingness to say la adri (I don't know) was considered a mark of genuine scholarship, not a failure of it. The scholar who knew the limits of their knowledge was more trustworthy than the one who answered everything with confidence.

Why This Matters Theologically

Claiming knowledge you do not have in religious matters is not merely an intellectual error. It is a form of speaking about God without knowledge, one of the most serious prohibitions in Islam.

The Quran says: "Do not pursue that of which you have no knowledge." (17:36). And: "Say: My Lord has only forbidden immorality (what is apparent and what is concealed) and sin, and oppression without right, and that you associate with God that for which He has not sent down authority, and that you say about God what you do not know." (7:33). Speaking about God without knowledge is named in 7:33 alongside the gravest prohibitions (including shirk and oppression) which signals how seriously the Quran treats the offence, even if the specific weight of each prohibition differs.

A Muslim who answers a religious question they are not qualified to answer (even with good intentions) is potentially leading others astray on matters that affect their worship, their family life, their financial dealings, and their relationship with God. The responsibility is enormous.

The Practical Guidance

For ordinary Muslims: You are not required to have an answer to every religious question. When you do not know, say so. Then direct the person to someone qualified. "I don't know, but let me find out" or "You should ask a scholar" are complete and honourable answers.

For community figures: Imams, teachers, and community leaders who are not trained scholars should be clear about the limits of their knowledge. There is no shame in saying: "This is beyond what I am trained to answer: here is someone qualified."

For the person asking: Do not demand certainty from those who should not be certain. Do not prefer the confident wrong answer to the honest "I don't know." The confidence of a speaker is not evidence of their knowledge.

The Companion Model

The companions of the Prophet ﷺ (the generation closest to revelation) would frequently say "I don't know" and refer questioners to each other. Umar ibn al-Khattab would consult the companions collectively on difficult questions. Abu Bakr, when asked about the meaning of a verse he was uncertain about, said: "What sky would shade me and what earth would carry me if I spoke about God's book with what I do not know?" (reported by Ibn Abi Mulayka and cited by Ibn Sa'd and others).

This is the standard. The greatest Muslims in history modelled humility about the limits of their knowledge. The contemporary culture of instant answers to every question (driven by social media incentives that reward confidence over accuracy) is the inverse of this tradition.
