It was narrated that Zirr bin Hubaish said: “I went to Safwân bin ‘Assâl Al-Murâdi and he said: ‘What brought you here?’ I said: ‘I am seeking knowledge.’ He said: I heard the Messenger of Allah ﷺ say: “There is no one who goes out of his house in order to seek knowledge, but the angels lower eir wings in approval of his tion.” (Hasan)
