باب إِعْطَاءِ الْمُؤَلَّفَةِ قُلُوبُهُمْ عَلَى الإِسْلاَمِ وَتَصَبُّرِ مَنْ قَوِيَ إِيمَانُهُ ‏
Sahih Muslim 1060 a

Rafi' b. Khadij reported that the Messenger of Allah; (ﷺ) gave to Abu Sufyan b. Harb and Safwan. b. Umayya and 'Uyaina b. Hisn and Aqra' b. Habis, i.e. to every one of these persons, one hundred camels, and gave to 'Abbas b. Mirdas less than this number. Upon this 'Abbas b. Mirdis said:

You allot the share of my booty and that of my horse between 'Uyaina and Aqra'. Both Uyaina and Aqra' are in no way more eminent than Mirdas (my father) in the assembly. I am in no way inferior to any one of these persons. And he who is let down today would not be elevated. He (the narrator) said: The Messenger of Allah (ﷺ) then completed one hundred camels for him.
حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَرَ الْمَكِّيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ عُمَرَ بْنِ سَعِيدِ بْنِ مَسْرُوقٍ، عَنْ أَبِيهِ، عَنْ عَبَايَةَ بْنِ رِفَاعَةَ، عَنْ رَافِعِ بْنِ خَدِيجٍ، قَالَ أَعْطَى رَسُولُ اللَّهِ صلى الله عليه وسلم أَبَا سُفْيَانَ بْنَ حَرْبٍ وَصَفْوَانَ بْنَ أُمَيَّةَ وَعُيَيْنَةَ بْنَ حِصْنٍ وَالأَقْرَعَ بْنَ حَابِسٍ كُلَّ إِنْسَانٍ مِنْهُمْ مِائَةً مِنَ الإِبِلِ وَأَعْطَى عَبَّاسَ بْنَ مِرْدَاسٍ دُونَ ذَلِكَ ‏.‏ فَقَالَ عَبَّاسُ بْنُ مِرْدَاسٍ أَتَجْعَلُ نَهْبِي وَنَهْبَ الْعُبَيْدِ بَيْنَ عُيَيْنَةَ وَالأَقْرَعِ فَمَا كَانَ بَدْرٌ وَلاَ حَابِسٌ يَفُوقَانِ مِرْدَاسَ فِي الْمَجْمَعِ وَمَا كُنْتُ دُونَ امْرِئٍ مِنْهُمَا وَمَنْ تَخْفِضِ الْيَوْمَ لاَ يُرْفَعِ قَالَ فَأَتَمَّ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم مِائَةً ‏.‏
