When the Prophet ﷺ alighted at Marr az-Zahran, al-Abbas said: I thought, I swear by Allah, if the Messenger of Allah ﷺ 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 Messenger of Allah ﷺ 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 Messenger of Allah ﷺ, 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 Messenger of Allah ﷺ 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 Messenger of Allah ﷺ and he embraced Islam. I said: Messenger 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.

لَمَّا نَزَلَ رَسُولُ اللهِ ﷺ بِمَرِّ الظَّهْرَانِ قَالَ الْعَبَّاسُ قُلْتُ وَاللهِ لَئِنْ دَخَلَ رَسُولُ اللهِ ﷺ مَكَّةَ عَنْوَةً قَبْلَ أَنْ يَأْتُوهُ فَيَسْتَأْمِنُوهُ إِنَّهُ لَهَلَاكُ قُرَيْشٍ فَجَلَسْتُ عَلَى بَغْلَةِ رَسُولِ اللهِ ﷺ فَقُلْتُ لَعَلِّي أَجِدُ ذَا حَاجَةٍ يَأْتِي أَهْلَ مَكَّةَ فَيُخْبِرُهُمْ بِمَكَانِ رَسُولِ اللهِ ﷺ لِيَخْرُجُوا إِلَيْهِ فَيَسْتَأْمِنُوهُ وَإِنِّي لَأَسِيرُ سَمِعْتُ كَلَامَ أَبِي سُفْيَانَ وَبُدَيْلِ بْنِ وَرْقَاءَ فَقُلْتُ يَا أَبَا حَنْظَلَةَ فَعَرَفَ صَوْتِي قَالَ أَبُو الْفَضْلِ؟ قُلْتُ نَعَمْ قَالَ مَا لَكَ فِدَاكَ أَبِي وَأُمِّي؟ قُلْتُ هَذَا رَسُولُ اللهِ ﷺ وَالنَّاسُ قَالَ فَمَا الْحِيلَةُ؟ قَالَ فَرَكِبَ خَلْفِي وَرَجَعَ صَاحِبُهُ فَلَمْ أُصْبِحْ غَدَوْتُ بِهِ عَلَى رَسُولِ اللهِ ﷺ فَأَسْلَمَ قُلْتُ يَا رَسُولَ اللهِ إِنَّ أَبَا سُفْيَانَ رَجُلٌ يُحِبُّ هَذَا الْفَخْرَ فَاجْعَلْ لَهُ شَيْئًا قَالَ نَعَمْ مَنْ دَخَلَ دَارَ أَبِي سُفْيَانَ فَهُوَ آمِنٌ وَمَنْ أَغْلَقَ عَلَيْهِ دَارَهُ فَهُوَ آمِنٌ وَمَنْ دَخَلَ الْمَسْجِدَ فَهُوَ آمِنٌ قَالَ فَتَفَرَّقَ النَّاسُ إِلَى دُورِهِمْ وَإِلَى الْمَسْجِدِ
