Anecdotes
Before becoming a great general, Abdallah ibn Saad was one of the scribes tasked with recording the revelations of the Quran in Medina. According to several accounts, he abandoned this role and fell out with the new religion, which placed him on a list of outlaws during the capture of Mecca in 630.
Sentenced to death, Abdallah owed his survival to his foster brother, the future caliph Uthman, who brought him before the Prophet Muhammad and pleaded at length to obtain his pardon. Mercy was finally granted, and the man once outlawed later became one of the most powerful governors of the Empire.
In 647, during his campaign in Ifriqiya (present-day Tunisia), his army faced that of the Byzantine exarch Gregory near Sufetula (Sbeitla). Tradition holds that Gregory promised an enormous reward to whoever killed the Arab leader; Abdallah is said to have then promised the same sum and Gregory's daughter to whoever struck down the exarch.
In 655, Abdallah commanded the first great Muslim fleet at the Battle of the Masts (Dhat al-Sawari), facing an immense Byzantine fleet led, according to the sources, by the Emperor Constans II himself. The ships were lashed together to turn the naval engagement into a boarding melee, for which the Arabs, not seafarers by tradition, were better prepared in hand-to-hand combat.
When the great discord (fitna) broke out and his protector Uthman was assassinated in 656, Abdallah lost his position and chose to withdraw from political life. According to one tradition, he prayed to God that his last morning prayer might be the final act of his life: he is said to have died while prostrating himself, at Ramla or Ascalon.
