Surah Al-Maidah, verse 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 ﴿١٠١﴾

5:101 O you who believe, do not ask about things which, if they are made known to you, would only cause you hardship. If you inquire about them while the Qur’an is being revealed, they will be made known to you. Allah has pardoned you for it. Allah is All-Forgiving, Most Forbearing
