That the Prophet (ﷺ) said: "On the day of His Lord spoke to him, Musa was wearing a wool Kisa', a wool Jubbah, a wool Kummah, wool pants, and his sandals were made of the skin of a dead donkey."

[Abu 'Eisa said:] This Hadith is Gharib, we do not know of it except from the the narration of Humaid Al-A'raj. And Humaid - Ibn 'Ali Al-A'raj - I Heard Muhammad saying: "Humaid bin 'Ali Al-A'raj is Munkar in Hadith." While Humaid ibn Qais Al-A'raj Al-Makki, the companion of Mujahid is trustworthy. The Kummah is a small cap.
