Narrated Al-Musayyab bin Najabah:
'Ali bin Abi Talib said: Indeed every Prophet is given seven select attendants - or he said: guards - and I was given fourteen. We said: Who are they? He said: 'Myself, my two sons (Al-Hasan and Al-Husain), Ja'far, Hamzah, Abu Bakr, 'Umar, Mus'ab bin 'Umair, Bilal, Salman, 'Ammar, Al-Miqdad, Hudhaifah, Abu Dharr, and 'Abdullah bin Mas'ud.'
