Arabic hadith text
حَدَّثَنِي أَحْمَدُ بْنُ أَبِي الطَّيِّبِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ مُجَالِدٍ، حَدَّثَنَا بَيَانُ بْنُ بِشْرٍ، عَنْ وَبَرَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ هَمَّامٍ، قَالَ سَمِعْتُ عَمَّارًا، يَقُولُرَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَمَا مَعَهُ إِلاَّ خَمْسَةُ أَعْبُدٍ وَامْرَأَتَانِ وَأَبُو بَكْرٍ.
Translation
Narrated `Ammar
I saw Allah's Messenger (ﷺ) and there was none with him but five slaves, two women and Abu Bakr (i.e. those were the only converts to Islam then).
