Banu Hashim's disagreed with Abu Bakr .as Caliph, ‘Ali refused to support Abu Bakr and Abu Sufyan tried to persuade ‘Ali to arrange a coup d'etat. "Finally the Muhajirs, Ansars and Quraish, who were pioneers in Islam and supporters of Islam, and relatives of the Prophet, could not unite to form a government peacefully. This made other Arab tribes disillusioned, and finally they gave up hope of having any vote, or chance in the government.

Hence most of them objected to Abu Bakr as Caliph and refused to pay him the due alms tax. Some foreign scholars take this as heresy, and as evidence of the advance of Islam by the sword in Arabia. That is not true however, because those people whom Abu Bakr fought as heretics, had remained faithful to Islam. They were of two groups.

The group who believed that the alms tax was the Prophet's levy, and after his death no one was entitled to ask for it; so they refused to pay it to Abu Bakr — and for this he fought them. ‘Omar pleaded on behalf of those people saying, "The Prophet used to say, ‘I fight people until they believe in one God, and anybody who believes in God, his blood and belongings will be protected." The group who did not believe in the faith. In fact they were not Muslims.

The Islamic state at Abu Bakr's time cared about only carrying out death sentences, and was not concerned about heretics returning to Islam." Yet, according to Islam, as pointed out by Dr. Hassan Ebrahim, "Any heretic must have three days to discuss his views with the religious authorities. Hence — ‘Let accusations be proved before he perishes, and he who remains safe does so by proof." To clear up the matter, we refer to some views by Sunnis leaders.

"Imam Abu Hanifah says: ‘The shortest time allowed for a person to make up his mind is three days. If the heretic asks for grace, give him three days to discuss points.” "Imam Malik says: ‘A heretic, be he slave or free, man or woman, give him three days from the day proven to be heretic. He can have food and must not be tortured.” "Imam Shafe‘i says: ‘Heretic, man or woman, must be respected because he or she was a Muslim sometime.

Some say give him or her, three days grace.’ "Imam Hanbal says: ‘Heretics, men or women, adult and if not insane must be invited to Islam for three days.’ "As well as the above views, it is not right to say that a Muslim has renounced his faith just by guess work, unless every Muslim says he is a heretic.
