Musnad Ahmad 1414

It was narrated that Mutarrif said: We said to az-Zubair (رضي الله عنه): “O Abu "Abdullah, what brought you here? You let the caliph down until he was killed, then you came seeking vengeance for him?” Az-Zubair (رضي الله عنه) said: “At the time of the Prophet (ﷺ), Abu Bakr, "Umar and "Uthman and me, we read the verse: “And fear the Fitnah (affliction and trial) which affects not in particular (only those) of you who do wrong (but it may afflict all the good and the bad people).” [al-Anfal 8:25]. But we never knew that it referred to us until the turmoil befell us.”
