يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَسْـَٔلُوا۟ عَنْ أَشْيَآءَ إِن تُبْدَ لَكُمْ تَسُؤْكُمْ وَإِن تَسْـَٔلُوا۟ عَنْهَا حِينَ يُنَزَّلُ ٱلْقُرْءَانُ تُبْدَ لَكُمْ عَفَا ٱللَّهُ عَنْهَا ۗ وَٱللَّهُ غَفُورٌ حَلِيمٌۭ
O you who have believed, do not ask about things which, if they are shown to you, will distress you. But if you ask about them while the Qur'an is being revealed, they will be shown to you. Allah has pardoned that which is past; and Allah is Forgiving and Forbearing.
Commentary
The Prohibition of Asking Unnecessary Questions
These verses warn people who keep investigating unnecessarily into Divine injunctions. So fond and bent are they in this exercise that they would go to the outer limit of asking questions even about in-junctions which have not been prescribed at all and for which there is really no genuine need that they be asked. In this verse, such people have been instructed not to ask questions lest they are subjected to some trial, or they have to face disgrace as a result of the disclosure of their secrets.
The Background of the Revelation
As narrated in Sahib Muslim, the background or the cause of the revelation of these verses is as follows. When the verse concerning the obligation of Hajj was revealed, Sayyidna Al-Aqra` ibn Habis ؓ asked: ` Have we been obligated with Hajj every year?' The Holy Prophet ﷺ did not answer that question. He asked again. The Holy Prophet still remained silent. When he asked a third time, the Holy Prophet ﷺ reprimanded him by saying: If, in answer to your question, I had said, ` Yes, the Hajj is obligatory every year' - so it would have become, and you would have been unable to do it. After that, he added: Things about which I give you no command, leave them as they are. Do not ask questions by digging and prying into them. Communities before you have been damned eternally through this very proliferation of questioning because they, questions after questions about what Allah and His Messenger did not make obligatory on them, and in consequence of their unnecessary enquiry, these optional things were made obligatory - and then, they got involved in the unfortunate practice of disobeying these. Your estab-lished routine should be: Do what I order you to do, with the best of your ability, and leave what I order you not to do (that is, do not dig and pry into things about which no injunctions are given).
There is No Nubuwwah (Prophethood) and Wahy (Revelation) after the Holy Prophet ﷺ
It has also been tacitly said in this verse: وَإِن تَسْأَلُوا عَنْهَا حِينَ يُنَزَّلُ الْقُرْآنُ تُبْدَ لَكُمْ : ` and if you ask about them while the Qur'an is being revealed, they will be disclosed to you (through revelation).' Here, by restricting it with the time duration of the revelation of the Qur'an, the indication given is that it will be after the completion of the revelation of the Qur'an, that the process of Prophethood (Nubuwwah) and Revelation (Wahy) will be discontinued.
Though, after the discontinuation of this process of Prophethood and Revelation, the consequences that new injunctions may come, things not obligatory may become obligatory or someone's secret may be disclosed through revelation are not likely to take effect - but, minting unnecessary questions, falling for investigations into them or asking about things for which there is no need, shall still remain prohibited, even after the discontinuation of the process of Prophethood. The reason is simple. This is a waste of time - your own and that of others. The Holy Prophet ﷺ has said:
مِن حُسنِ اِسلامِ المرَءِ تَرکُہ مَالَایَعنِیہِ
One of the qualities making someone a good Muslim is that one leaves what …
