Sahih Muslim , Book 6, Hadith 87 (In-Book) ⓘ
Jabir b. 'Abdullah reported: The Messenger of Allah bought a camel from me. When he came back to Medina, he ordered me to come to the mosque and observed two rak'ahs of prayer.
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَارِبٍ، سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ اشْتَرَى مِنِّي رَسُولُ اللَّهِ صلى الله عليه وسلم بَعِيرًا فَلَمَّا قَدِمَ الْمَدِينَةَ أَمَرَنِي أَنْ آتِيَ الْمَسْجِدَ فَأُصَلِّيَ رَكْعَتَيْنِ .
