Mutarrif says that once we said to Sayyiduna Zubair (may Allah be pleased with him), "O Abu Abdullah! For what purpose have you people come? You people lost a caliph until he was martyred, and now you are demanding retribution for him?" Sayyiduna Zubair (may Allah be pleased with him) replied, "In the time of the Prophet (peace and blessings be upon him), Sayyiduna Abu Bakr as-Siddiq, Sayyiduna Umar al-Faruq, and Sayyiduna Uthman al-Ghani (may Allah be pleased with them), we used to recite this verse of the Qur'an: «﴿وَاتَّقُوا فِتْنَةً لَا تُصِيبَنَّ الَّذِينَ ظَلَمُوا مِنْكُمْ خَاصَّةً﴾ [الأنفال: 25] » 'And fear a trial which will not strike those who have wronged among you exclusively (but will affect everyone),' but we did not think that it would apply to us, until this trial befell us."
