It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that, concerning this saying of Allah, the Mighty and Majestic: "So when his Lord manifested His glory to the mountain, He made it crumble to dust" [Surah al-A'raf: 143] , the Prophet (peace and blessings be upon him) (while explaining it) placed his thumb on the joint of the little finger of the right hand (meaning that He manifested only a very small portion of His glory). Hammad said: Humayd said to Thabit (the narrator): "Do you narrate something like this?!" So Thabit struck Humayd on the chest with his hand and said: "The Messenger of Allah (peace and blessings be upon him) used to narrate it, and I should not narrate it?!" This hadith is sahih (authentic) on the condition of Imam Muslim.
