Al-Abbas ibn AbdulMuttalib brought AbuSufyan ibn Harb to the Messenger of Allah (ﷺ) in the year of the conquest (of Mecca). So he embraced Islam at Marr az-Zahran. Al-Abbas said to him: Messenger of Allah, AbuSufyan is a man who likes taking this pride, if you may do something for him. He said: Yes, he who enters the house of AbuSufyan is safe, and he who closes his door is safe.
