Narrated Abdullah Ibn Abbas:
When the Prophet (peace_be_upon_him) alighted at Marr az-Zahran, al-Abbas said: I thought, I swear by Allah, if the Apostle of Allah (peace_be_upon_him) enters Mecca with the army by force before the Quraysh come to him and seek protection from him, it will be their total ruin. So I rode on the mule of the Apostle of Allah (peace_be_upon_him) and thought, Perhaps I may find a man coming for his needs who will to the people of Mecca and inform them of the position of the Apostle of Allah (peace_be_upon_him), so that they may come to him and seek protection from him. While I was on my way, I heard AbuSufyan and Budayl ibn Warqa' speaking.
I said: O AbuHanzalah! He recognized my voice and said: AbulFadl? I replied: Yes. He said: who is with you, may my parents be a sacrifice for you? I said: Here are the Apostle of Allah (peace_be_upon_him) and his people (with him).
He asked: Which is the way out? He said: He rode behind me, and his companion returned. When the morning came, I brought him to the Apostle of Allah (peace_be_upon_him) and he embraced Islam.
I said: Apostle of Allah, AbuSufyan is a man who likes this pride, do something for him. He said: Yes, he who enters the house of AbuSufyan is safe; he who closes the door upon him is safe; and he who enters the mosque is safe. The people scattered to their houses and in the mosque.
