The meaning of the verse is: when the condition of your hand and the radiance you see from it have passed, put it into your bosom, and it will return to its former state. “The wing” means the entire hand; it is also said to mean the upper arm. Ata related from Ibn Abbas, may Allah be pleased with him: Allah commanded him to draw his hand to his chest (1), so that the fear which had seized him upon seeing the snake would leave him. He said: No one who is afraid after Moses, when he places his hand upon his chest, will remain afraid. Mujahid said: Whoever is terrified and draws his two arms close to himself will be rid of his fright.
It is also said that what is meant by drawing in the wing is composure: that is, calm your fear and lower your side over yourself, for one who is afraid is apt to have his heart agitated and his body tremble. Similar to this is His saying: “And lower to them the wing of humility out of mercy” (al-Isra' 17:24)—meaning, treat them gently—and His saying: “And lower your wing to those believers who follow you” (al-Shu'ara' 26:215), meaning: be gentle with them and show them kindness.
Al-Farra' said: By “wing” He meant the staff; that is, draw your staff close to yourself. It is also said that rahb means “sleeve” in the language of Himyar. Al-Asma'i said: I heard one of the Bedouins say, “Give me what is in your rahb,” meaning, “in your sleeve.” Thus, the meaning is: draw your hand close to yourself and take it out of your sleeve, because he had taken hold of the staff while his hand was in his sleeve. “These two” means the staff and the white hand; “two proofs” means two signs, “from your Lord to Pharaoh and his chiefs. Indeed, they were a defiantly disobedient people.”
“He said, ‘My Lord, I killed one of their people, and I fear that they will kill me (33). And my brother Aaron is more eloquent in speech than I am, so send him with me as a supporting helper to confirm me. Indeed, I fear that they will deny me (34).’”
“He said, ‘My Lord, I killed one of their people, and I fear that they will kill me.’”
“And my brother Aaron is more eloquent in speech than I am.” He said this because of the impediment in his tongue caused by placing the coal in his mouth (2). “So send him with me as a supporting helper”: that is, as an aid. One says, “I supported him,” meaning, “I assisted him.” Nafi' read ridan, with the dal carrying a fathah—
