Усман ибн Аффан
As Umar lay dying after being stabbed by Abu-Lu'lu'ah on November 1, 644, he summoned Uthman ibn Affan, Ali, Talhah, Zubayr ibn al-Awam, Abdur Rahman bin Awf, and Sa`d ibn Abi Waqqas and instructed them to consult among themselves and with the Muslims for three days and choose a successor.
