According to the Hudaibiyah pact the Arab tribes had the option to be allied with the Quraish or the Muslims. In pursuance of these terms the Arabs of the Banu Bakr allied themselves with the Quraish, while the tribe of the Banu Khuza'ah allied themselves with the Muslims.
In disregard of the terms of the treaty of Hudaibiyah, the Banu Bakr attacked the Banu Khuza'ah, and even when the Banu Khuza'ah sought the sanctuary of the Kaaba, many of them were killed. The Banu Khuza'ah thereupon appealed to the Holy Prophet to come to their aid. The Holy Prophet assured them that in pursuance of the terms of the Hudaibiyah pact, the Muslims would come to their assistance.
The Holy Prophet thereupon took up the matter with the Quraish and offered them three alternatives. They were required in the first instance to pay the blood money for the victims of the high handedness of the Banu Bakr. In the alternative they should terminate their alliance with Banu Bakr. f either of these alternatives was not agreed to, then as the last resort the Hudaibiyah pact should be considered to be abrogated.
The Quraish who were already feeling unhappy at the visit of the Muslims to Makkah decided to abrogate the treaty of Hudaibiyah. The Holy Prophet welcomed this move on the part of the Quraish and declared that the Quraish would have in hear the consequences of the breach of faith.
The Quraish soon realized that they had made a mistake in abrogating the treaty of Hudaibiyah. Abu Sufyan the leader of the Quraish visited Madina to make amends. He sought an interview with the Holy Prophet to discuss the issue. The Holy Prophet refused to see him because of the Quraish breach of faith. One of the daughters of Abu Sufyan was a wife of the Holy Prophet. Abu Sufyan wanted her to plead his case with the Holy Prophet, but she refused. Abu Sufyan was related to Uthman. He wanted Othrnan to intercede with the Holy Prophet on his behalf. Uthman politely refused to oblige him. Abu Sufyan returned disappointed from Madina.
