Sahih al-Bukhari, Book 43, Hadith 1 (In-Book) ⓘ

Narrated Jabir bin `Abdullah: While I was in the company of the Prophet in one of his Ghazawat, he asked, "What is wrong with your camel? Will you sell it?" I replied in the affirmative and sold it to him. When he reached Medina, I took the camel to him in the morning and he paid me its price.

حَدَّثَنَا مُحَمَّدٌ، أَخْبَرَنَا جَرِيرٌ، عَنِ الْمُغِيرَةِ، عَنِ الشَّعْبِيِّ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ غَزَوْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ كَيْفَ تَرَى بَعِيرَكَ أَتَبِيعُنِيهِ ‏" ‏‏.‏ قُلْتُ نَعَمْ‏.‏ فَبِعْتُهُ إِيَّاهُ، فَلَمَّا قَدِمَ الْمَدِينَةَ غَدَوْتُ إِلَيْهِ بِالْبَعِيرِ، فَأَعْطَانِي ثَمَنَهُ‏.‏
