Pro Abu Sufyan

حَدَّثَنِي عَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ الْعَنْبَرِيُّ، وَأَحْمَدُ بْنُ جَعْفَرٍ الْمَعْقِرِيُّ، قَالاَ حَدَّثَنَا النَّضْرُ، - وَهُوَ ابْنُ مُحَمَّدٍ الْيَمَامِيُّ - حَدَّثَنَا عِكْرِمَةُ، حَدَّثَنَا أَبُو زُمَيْلٍ، حَدَّثَنِي ابْنُ عَبَّاسٍ، قَالَ كَانَ الْمُسْلِمُونَ لاَ يَنْظُرُونَ إِلَى أَبِي سُفْيَانَ وَلاَ يُقَاعِدُونَهُ فَقَالَ لِلنَّبِيِّ صلى الله عليه وسلم يَا نَبِيَّ اللَّهِ ثَلاَثٌ أَعْطِنِيهِنَّ قَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ عِنْدِي أَحْسَنُ الْعَرَبِ وَأَجْمَلُهُ أُمُّ حَبِيبَةَ بِنْتُ أَبِي سُفْيَانَ أُزَوِّجُكَهَا قَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ وَمُعَاوِيَةُ تَجْعَلُهُ كَاتِبًا بَيْنَ يَدَيْكَ ‏.‏ قَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ وَتُؤَمِّرُنِي حَتَّى أُقَاتِلَ الْكُفَّارَ كَمَا كُنْتُ أُقَاتِلُ الْمُسْلِمِينَ ‏.‏ قَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ أَبُو زُمَيْلٍ وَلَوْلاَ أَنَّهُ طَلَبَ ذَلِكَ مِنَ النَّبِيِّ صلى الله عليه وسلم مَا أَعْطَاهُ ذَلِكَ لأَنَّهُ لَمْ يَكُنْ يُسْئَلُ شَيْئًا إِلاَّ قَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏

Ibn Abbas reported that the Muslims neither looked to Abu Sufyan (with respect) nor did they sit in his company. he (Abu Sufyan) said to Allah's Apostle (ﷺ): Allah's Apostle, confer upon me three things. He replied in the affirmative. He (further) said: I have with me the most handsome and the best (woman) Umm Habiba, daughter of Abu Sufyan; marry her, whereupon he said: Yes. And he again said: Accept Mu'awiya to serve as your scribe. He said: Yes. He again said: Make me the commander (of the Muslim army) so that I should fight against the unbelievers as I fought against the Muslims. He said: Yes. Abu Zumnail said: If he had not asked for these three things from Allah's Apostle (ﷺ), he would have never conferred them upon him, for it was (his habit) to accede to everybody's (earnest) request.
