Sahih al-Bukhari 3971
Narrated `Abdur-Rahman bin `Auf:
"I had an agreement with Umaiya bin Khalaf (that he would look after my relatives and property in 
Mecca, and I would look after his relatives and property in Medina)." `Abdur-Rahman then mentioned 
the killing of Umaiya and his son on the day of Badr, and Bilal said, "Woe to me if Umaiya remains 
safe (i.e. alive) . "
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي يُوسُفُ بْنُ الْمَاجِشُونِ، عَنْ صَالِحِ بْنِ إِبْرَاهِيمَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ عَبْدِ الرَّحْمَنِ، قَالَ كَاتَبْتُ أُمَيَّةَ بْنَ خَلَفٍ، فَلَمَّا كَانَ يَوْمُ بَدْرٍ، فَذَكَرَ قَتْلَهُ وَقَتْلَ ابْنِهِ، فَقَالَ بِلاَلٌ لاَ نَجَوْتُ إِنْ نَجَا أُمَيَّةُ‏.‏
