The Quran

يا أَيُّهَا الَّذينَ آمَنوا لا تَكونوا كَالَّذينَ آذَوا موسىٰ فَبَرَّأَهُ اللَّهُ مِمّا قالوا ۚ وَكانَ عِندَ اللَّهِ وَجيهًا

Muhammad Asad

O YOU who have attained to faith! Be not like those [children of Israel] who gave offence to Moses, and [remember that] God showed him to be innocent of whatever they alleged [against him or demanded of him]:¹ for of great honour was he in the sight of God.

This is an allusion to the aspersions occasionally cast upon Moses by some of his followers and mentioned in the Old Testament (e.g., Numbers xii, 1-13), as well as to the blasphemous demands of which the Qur'an speaks - e.g., "O Moses, indeed we shall not believe thee until we see God face to face" (2:55) or. "Go forth, thou and thy Sustainer, and fight, both of you!" (5:24). These instances are paralleled here with the frequently cited accusations that Muhammad had "invented" the Qur'an and then falsely attributed it to God, that he was a madman, and so forth. as well as with frivolous demands to prove his prophethood by bringing about miracles or - as is restated in verse 63 of this surah - by predicting the date of the Last Hour.
