Qur'an 5:101

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَسْـَٔلُوا۟ عَنْ أَشْيَآءَ إِن تُبْدَ لَكُمْ تَسُؤْكُمْ وَإِن تَسْـَٔلُوا۟ عَنْهَا حِينَ يُنَزَّلُ ٱلْقُرْءَانُ تُبْدَ لَكُمْ عَفَا ٱللَّهُ عَنْهَا ۗ وَٱللَّهُ غَفُورٌ حَلِيمٌ

O ye who believe! Ask not of things which, if they were made unto you, would trouble you; but if ye ask of them when the Qur'an is being revealed, they will be made known unto you. Allah pardoneth this, for Allah is Forgiving, Clement.
