At this time...
At this time, the following revelation came down: "Oh you believe, if a transgressor comes to you with news, try to verify it, lest you inflict damage on people unwittingly; then you may consequently regret your hasty action. (49:6) Walid continued in his non-Islamic way for the rest of his life. He used to drink wine and several witnesses testified to the Caliph that they had witnessed Walid drunk while leading a congregational prayer.
Upon the testimony of good witnesses, Walid was lashed eighty times and was dismissed by the Caliph. The Caliph was expected to replace this transgressor with a good companion of the Prophet but, instead, he replaced Walid with Sa'id Ibn Al-’As, one of his Umayyad relatives.
The Of Medina Wrote To The Outside Medina Al -Tabari reported that when people witnessed what 'Uthman had done, the companions living in Medina wrote to the companions living in other provinces: "You have left Medina to endeavor in the way of God and promote the religion of Muhammad. The religion of Muhammad has been corrupted. Come back and straighten the religion of Muhammad." The companions came from every province and killed the Caliph.
(Al-Tabari, al-Ta'rikh, part 4, page 367) Talhah Talhah Ibn Ubaydullah was one of the biggest agitators against 'Uthman. It is reported that Imam Ali said to Talhah: "I ask you in the name of Allah to deter people from attacking 'Uthman." Talhah retorted: "No, by God, until the Umayyad returns to the people their rights." 'Uthman was the head of the Umayyads. (Al-Tabari, page 405) 'Uthman was besieged in Medina while Imam Ali was in Khaybar.
The Imam came to Medina and found people gathering at the residence of Talhah, one of the influential people in Medina. 'Uthman came to Imam Ali and said: "You owe me my Islamic right and the right of brotherhood and relationship.
If I have none of these rights and if I were in the pre-Islamic era, it would still be a shame for a descendant of Abd-Manaf (of whom both Ali and 'Uthman are descendants) to let a man of Taym (Talhah) rob us of our authority." Imam Ali said to 'Uthman: "You shall be informed of what I do." The Imam went to Talhah's house. There were a lot of people there.
Imam Ali spoke to Talhah saying: "Talhah, what is this predicament in which you have fallen?" Talhah said: "Abu al-Hasan, it is too late." The Imam went to the treasury and ordered people to open it. Unable to find the key, he broke the door and distributed some of the money among the people.
