Qur'an 2:97 · Al-Baqara

قُلْ مَن كَانَ عَدُوًّۭا لِّجِبْرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلْبِكَ بِإِذْنِ ٱللَّهِ مُصَدِّقًۭا لِّمَا بَيْنَ يَدَيْهِ وَهُدًۭى وَبُشْرَىٰ لِلْمُؤْمِنِينَ

(97) Say, "Whoever is an enemy to Gabriel - it is [none but] he who has brought it [i.e., the Qur’ān] down upon your heart, [O Muḥammad], by permission of Allāh, confirming that which was before it and as guidance and good tidings for the believers."
