Sahih al-Bukhari, Book 62, Hadith 12 (In-Book) ⓘ
Narrated `Ammar: I saw Allah's Messenger and there was none with him but five slaves, two women and Abu Bakr (i.e. those were the only converts to Islam then).
حَدَّثَنِي أَحْمَدُ بْنُ أَبِي الطَّيِّبِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ مُجَالِدٍ، حَدَّثَنَا بَيَانُ بْنُ بِشْرٍ، عَنْ وَبَرَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ هَمَّامٍ، قَالَ سَمِعْتُ عَمَّارًا، يَقُولُ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَمَا مَعَهُ إِلاَّ خَمْسَةُ أَعْبُدٍ وَامْرَأَتَانِ وَأَبُو بَكْرٍ.
