The Messenger of Allah ﷺ related a tradition in which he mentioned the words "Jibril and Mikal" and he pronounced them "Jibra'ila wa Mika'ila." Abu Dawud said: Khalaf said: I did not put the pen aside from writing letters (huruf) for forty years: nothing tired me (or made me incapable of writing), even Jibril and Mika'il did not tire me.
حَدَّثَ رَسُولُ اللَّهِ ﷺ حَدِيثًا ذَكَرَ فِيهِ جِبْرِيلَ وَمِيكَالَ فَقَرَأَ { جِبْرَائِلَ وَمِيكَائِلَ }
