"On the day of Quraiza's (siege), Messenger of Allah ﷺ said to Hassan bin Thabit, 'Abuse them (with your poems), and Jibril is with you.'" (Using translation from Bukhārī 4124)
أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ يَوْمَ قُرَيْظَةَ لِحَسَّانَ بْنِ ثَابِتٍ «اهْجُ الْمُشْرِكِينَ فَإِنَّ جِبْرِيلَ مَعَكَ»
