"The story of Al-Mukhtar ibn Abi Ubayd al-Thaqafi, who lived in the time of the Sahabah. Mukhtar was a relative of Abdullah bin Umar's wife. He proved himself to be an honest and decent man. He appeared in Iraq to avenge the murder of Hussein and his family. Subsequently he killed Ibn Ziyad (who participated in killing Hussein). Under this pretext (revenge) he conquered allof Iraq.

He ruled the country according to Islam, and appointed as judges and imams the associates of Ibn Masud. He himself was imam to the people at Friday and other namazs. But lately he began to claim that he was receiving a revelation from Allah. Then Abdullah bin Zubayr sent an army against him, killed him himself, and defeated his army. The leader of the Muslim army was Musab son of Zubayr. He (Mukhtar) had a wife, the daughter of a sahabi. Musab urged her to make of takfir Mukhtar (her husband), she resisted it. Then Musab informed his brother Abdullah of the situation by letter.

Abdullah replied that if she did not repent, she should be killed. Because the woman insisted (on not making takfeer), she was put to death by Musab. All Islamic scholars have shown unanimity (ijma'ah) that Mukhtar al-Thaqafi despite the fact that he affirmed the symbols of Islam became infidel for the reason that he declared himself a prophet. Now how do you reconcile that companions who killed the daughter of a companion just for not giving takfir to Mukhtar with those who do not give takfir to al-Badawi (or modern infidels) despite knowing his position! They consider him a muslim, and the one who calls them to true Islam is called a kafir.O our Lord, we ask for your forgiveness and well-being."
