[1] When Ṭalḥah and az-Zubayr reached Baṣrah it was Banū Tamīm who took active part in the movement to avenge ‘Uthmān’s blood and were foremost in fanning this mischief. Therefore, when ‘Abdullāh ibn al-‘Abbās took over as the Governor of Baṣrah, in view of their breach of faith and animosity, he thought they deserved harsh treatment and was to some extent severe with them. But in this tribe there were also a few sincere followers of Amīr al-mu’minīn. When they saw this behaviour of Ibn ‘Abbās with their tribe they sent a letter to Amīr al-mu’minīn through Jāriyah ibn Qadāmah wherein they complained of Ibn ‘Abbās’s harsh treatment. Thereupon, Amīr al-mu’minīn wrote this letter to Ibn ‘Abbās in which he instructed him to change his ways and to behave well with them, and has drawn his attention to the kinship existing between Banū Hāshim and Banū Tamīm. That kinship was this that Banū Hāshim and Banū Tamīm join the lineal line at Ilyās ibn Muḍar because Hāshim is the descendant of Mudrikah ibn Ilyās, while Tamīm is the descendant of Ṭābikhah ibn Ilyās.
