When Sayyiduna ‘Uthman (radiyallahu ‘anhu) was besieged, Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) sought permission to say a few words. After praising Allah, he said, “I heard Rasulullah (sallallahu ‘alayhi wa sallam) say, ‘You will encounter trials and difference of opinion after me.’ Someone said, ‘Who should we go to/What should we do, O Rasulullah?’ Nabi (sallallahu ‘alayhi wa sallam) saidwhilst pointing to Sayyiduna ‘Uthman(radiyallahu ‘anhu): ‘Go to the trustworthy one and his companions.’(Musnad Ahmad, vol. 2 pg. 345, Musannaf Ibn Abi Shaybah, Hadith: 32712 and Mustadrak Hakim, vol. 3 pg. 99)
