Sahih al-Bukhari 3161

Arabic

حَدَّثَنَا سَهْلُ بْنُ بَكَّارٍ، حَدَّثَنَا وُهَيْبٌ، عَنْ عَمْرِو بْنِ يَحْيَى، عَنْ عَبَّاسٍ السَّاعِدِيِّ، عَنْ أَبِي حُمَيْدٍ السَّاعِدِيِّ، قَالَ غَزَوْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم تَبُوكَ، وَأَهْدَى مَلِكُ أَيْلَةَ لِلنَّبِيِّ صلى الله عليه وسلم بَغْلَةً بَيْضَاءَ، وَكَسَاهُ بُرْدًا، وَكَتَبَ لَهُ بِبَحْرِهِمْ‏.‏
