Quran

 5:101

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ وَإِنْ تَسْأَلُوا عَنْهَا حِينَ يُنَزَّلُ الْقُرْآنُ تُبْدَ لَكُمْ عَفَا اللَّهُ عَنْهَا ۗ وَاللَّهُ غَفُورٌ حَلِيمٌ ﴿١٠١﴾

101. O you who believe! Do not ask about things, if disclosed to you, would trouble you. And if you inquire about them while the Quran is being revealed, they would become clear to you. Allah has pardoned this. Allah is Forgiving, Clement.
