Sahih al-Bukhari 4665

It is related that Ibn Abi Mulayka said, "There was a disagreement between them and I went to Ibn 'Abbas and said, 'Do you mean to fight Ibn az-Zubayr? Will you make the Haram of Allah profane?' He said, 'I seek refuge with Allah! Allah has written that Ibn az-Zubayr and the Banu Umayya (Umayyads) would permit it, but I, by Allah, would never make it lawful.' He said, 'People said said, "Give allegiance to Ibn az-Zubayr." I said, "How would this business be taken from him? His father was the helper of the Prophet, may Allah bless him and grant him peace, i.e. az-Zubayr. His grandfather was the companion in the Cave, i.e. Abu Bakr. His mother was "She of the two belts,' i.e. Asma'. His maternal aunt was the Mother of the Believers, i.e. 'A'isha, and his paternal aunt was the wife of the Prophet, may Allah bless him and grant him peace, i.e. Khadija. The paternal aunt of the Prophet, may Allah bless him and grant him peace, was his grandmother, i.e. Safiyya. Then he is abstinent in Islam, a reciter of Qur'an. By Allah, If they (the Umayyads) bring me close by kinship, they do so by close kinship, and if they rule me, noble peers rule me. So he preferred little Tuwayb, Usama and Hamd,"' he meant sub-tribes of the Banu Asad: the Banu Tuwayb, Banu Usama and Banu Asad. Ibn Abi'l-'As emerged advancing boldly, i.e. 'Abdu'l-Malik ibn Marwan, while he, i.e. Ibn az-Zubayr, fell back on his tail."
