Al-Musayyab bin Najabah:
"'Ali bin Abi Talib said: 'The Prophet SAW 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.'"
