The Prohibition of Unnecessary Questions

In this Ayah, Allah forbade the believers from asking the Prophet numerous questions about matters that did not occur yet. Similarly, Allah said,

يأَيُّهَا الَّذِينَ ءَامَنُواْ لاَ تَسْأَلُواْ عَنْ أَشْيَآءَ إِن تُبْدَ لَكُمْ تَسُؤْكُمْ وَإِن تَسْأَلُواْ عَنْهَا حِينَ يُنَزَّلُ الْقُرْءَانُ تُبْدَ لَكُمْ

Hostility to the Holy Prophet ﷺ had become so habitual to the Jews that they were always making insolent demands. Once they asked him to bring before them whole of the Qur'an all at once just as the Torah had been revealed.

In reprimanding them for making such improper demands on the prophets of their time, the verse reminds them how their forefathers too had done the same - for example, they had asked Sayyidna Musa (Moses علیہ السلام) to help them to see Allah openly with their physical eyes. In such cases, the intention of the Jews had never been to seek guidance or to satisfy their doubts or to strengthen their faith, but only to cast aspersions on a prophet, or to question the wisdom of Allah. The verse indicts this behavior as Kufr (infidelity). Such demands are improper, because there is a raison d'etre for everything Allah does, but divine wisdom alone knows what that is, and the creature has no right to determine the precise mode of his Creator's acts -- he should not even ask the why and wherefore of a divine action, but accept it and submit himself to the Divine Will.
