Say, to them: ‘Whoever is an enemy to Gabriel, let him die in exasperation — he it was that brought it, the Qur’ān, down upon your heart by the leave, by the command, of God, confirming what was before it, of scriptures, a guidance, from error, and good tidings, of Paradise, for the believers.
القرآن:٢:٩٧ –

قُلْ مَنْ كَانَ عَدُوًّا لِجِبْرِيلَ فَإِنَّهُ نَزَّلَهُ عَلَىٰ قَلْبِكَ بِإِذْنِ اللَّهِ مُصَدِّقًا لِمَا بَيْنَ يَدَيْهِ وَهُدًى وَبُشْرَىٰ لِلْمُؤْمِنِينَ  

{قل} لهم {من كان عدوّاً لجبريل} فليمت غيظاً {فإنه نزَّله} أي القرآن {على قلبك بإذن} بأمر {الله مصدقاً لما بين يديه} قلبه من الكتب {وهدىً} من الضلالة {وبشرى} بالجنة {للمؤمنين}.
