bukhari:2216Abū al-Nuʿmān > Muʿtamir b. Sulaymān from his father > Abū ʿUthmān > ʿAbd al-Raḥman b. Abū Bakr

We were with the Prophet ﷺ when a tall pagan with long matted unkempt hair came driving his sheep. The Prophet ﷺ asked him, "Are those sheep for sale or for gifts?" The pagan replied, "They are for sale." The Prophet ﷺ bought one sheep from him.  

البخاري:٢٢١٦حَدَّثَنَا أَبُو النُّعْمَانِ حَدَّثَنَا مُعْتَمِرُ بْنُ سُلَيْمَانَ عَنْ أَبِيهِ عَنْ أَبِي عُثْمَانَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرٍ ؓ قَالَ

كُنَّا مَعَ النَّبِيِّ ﷺ ثُمَّ جَاءَ رَجُلٌ مُشْرِكٌ مُشْعَانٌّ طَوِيلٌ بِغَنَمٍ يَسُوقُهَا فَقَالَ النَّبِيُّ ﷺ بَيْعًا أَمْ عَطِيَّةً أَوْ قَالَ أَمْ هِبَةً قَالَ لاَ بَلْ بَيْعٌ فَاشْتَرَى مِنْهُ شَاةً
