- .... And Sa'd called out, "O Abdur Rahman, finish before the people are led astray!" He replied, "I have looked and consulted, so do not let this group have any sway over yourselves."
Then he said to Ali, "You have the covenant of Allah and His pledge to act according to the Book of Allah, the Sunnah of His Messenger, and the practices of the two caliphs who came after him." Ali replied, "I hope to strive, indeed to act, to the best of my knowledge and ability." He said the same to Uthman, and Uthman replied, "Yes." Then he raised his head to the ceiling of the mosque, his hand in the hand of Uthman, and said, "O Allah, bear witness that I have placed what is in my neck regarding this in the neck of Uthman." So the people pledged allegiance to him.
