Sahih Muslim 715 t
Jabir b. 'Abdullah (Allah be pleased with them) reported:
Allah's Messenger (ﷺ) bought a camel from me for two 'uqiyas and a dirham or two dirhams. As he reached Sirar (a village near Medina), he commanded a cow to be slaughtered and it was slaughtered, and they ate of that, and as he (the Holy Prophet) reached Medina he ordered me to go to the mosque and offer two rak'ahs of prayer, and he measured for me the price of the camel and even made an excess payment to me.
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَارِبٍ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ اشْتَرَى مِنِّي رَسُولُ اللَّهِ صلى الله عليه وسلم بَعِيرًا بِوُقِيَّتَيْنِ وَدِرْهَمٍ أَوْ دِرْهَمَيْنِ - قَاَلَ - فَلَمَّا قَدِمَ صِرَارًا أَمَرَ بِبَقَرَةٍ فَذُبِحَتْ فَأَكَلُوا مِنْهَا فَلَمَّا قَدِمَ الْمَدِينَةَ أَمَرَنِي أَنْ آتِيَ الْمَسْجِدَ فَأُصَلِّيَ رَكْعَتَيْنِ وَوَزَنَ لِي ثَمَنَ الْبَعِيرِ فَأَرْجَحَ لِي ‏.‏
