[Ruiptuptubre]

I found this interesting from what Mu'awiyah (ra) wrote to 'Ali (ra) in al-'Aqd al-Fareed vol.5 pg.76 of Ibn 'Abd-Rabbuh al-Andalusi:

ولعمري ما حجتك على أهل الشام كحجتك على أهل البصرة [ هم ] كانوا قد أطاعوك ولم يطعك أهل [ الشام ] وإن طلحة والزبير كانا بايعاك ولم أبايعك [ أنا ] وأما فضلك في الاسلام وسابقتك وقرابتك من رسول الله صلى الله عليه وسلم فلست أدفعه

"I say that your argument against the people of al-Sham is not like your argument against the people of al-Basarah, for they had obeyed you but the people of al-Sham never obeyed you, also Talha and al-Zubair had given you a pledge of allegiance but I did not, and as for your virtue in Islam as one of the first to embrace it and your closeness to Rassul-Allah peace be upon him, then I do not deny this."
