Al-Ma'idah 5:101

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَسۡـَٔلُواْ عَنۡ أَشۡيَآءَ إِن تُبۡدَ لَكُمۡ تَسُؤۡكُمۡ وَإِن تَسۡـَٔلُواْ عَنۡهَا حِينَ يُنَزَّلُ ٱلۡقُرۡءَانُ تُبۡدَ لَكُمۡ عَفَا ٱللَّهُ عَنۡهَاۗ وَٱللَّهُ غَفُورٌ حَلِيمٞ 101

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
