Surah Al-Baqarah, ayah 97

2:97

قُلۡ مَن كَانَ عَدُوّٗا لِّـجِبۡرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلۡبِكَ بِإِذۡنِ ٱللَّهِ مُصَدِّقٗا لِّمَا بَيۡنَ يَدَيۡهِ وَهُدٗى وَبُشۡرَىٰ لِلۡمُؤۡمِنِينَ ٩٧

Qul man kāna 'aduwwal lijibrīla fa innahū nazzalahū 'alā qalbika bi idhnillāhi musaddiqal limā bayna yadayhi wahudan wabushrā lil-mu'minīn

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."
