"I heard the Prophet (s.a.w) narrating a hadith, not just once or twice, even seven times, but I heard him saying it more than that. I heard him saying: 'There was a man called Al-Kifl among the children of Isra'il who did not restrain himself from committing sins. A woman came to him and he gave her sixty Dinar so he could sleep with her. When he sat up from her, as a man sits up from a woman, she began to tremble and cry, so he said: "Why are you crying, did I do something to harm you?" She said: "No. But it is because of what I did, I only did so out of need." He said: "You did this without having done (it before), so leave me, and it (the money) is for you." And then he said: "By Allah! I will never disobey Allah after that." He died during the night and morning came with: " Indeed Allah has forgiven Al-Kifl" written upon his door."

“I came to Safwan bin `Assal Al-Muradi so he said to me: ‘What has brought you, O Zirr?’ So I said: ‘The desire for knowledge.’ So he said: ‘It has been conveyed to me that the angels lower their wings for the seeker of knowledge, out of pleasure with what he is doing.’” He said: “So I said to him: ‘Indeed there is something wavering’ - or - ‘some doubt in my chest concerning wiping over the Khuff after defecation. So have you retained anything from the Messenger of Allah (saws) concerning that?’ He said: ‘Yes, when we were travelers, he (saws) used to order us not to remove our Khuff for three days and nights, except from sexual impurity, but not from defecation, urination, and sleep.’” He said: “So I said: ‘So have you memorized anything from the Messenger of Allah (saws) concerning love?’ He said: ‘Yes, we were in one of our journeys with the Messenger of Allah (saws) when a man, a harsh, foolish Bedouin, who had been at the end of the group, called him with a loud voice, saying: “O Muhammad! O Muhammad!” So the people said to him “Mah! Indeed, you have been prohibited from this.” So the Messenger of Allah (saws) responded to him with similar to his voice: “Come.” So he said: “A man loves a people but he has not reached them?” He said: ‘So the Messenger of Allah (saws) said: “A man is with whomever he loves.”’ Zirr said: “He did not cease reporting to me until he had reported that Allah, the Mighty and Sublime, has appointed a gate in the west - its width is the distance of a seventy-year journey - for repentance: it shall not be locked until the sun rises from its direction, and that is the Statement of Allah, Blessed be He and Most High, of the Ayah: The Day some of the signs of your Lord come, no soul shall be benefited by its believing.”
