It is narrated from Ismail that he said: A certain man who used to sell wheat narrated to us, he said: When Hazrat Hudhaifa (may Allah be pleased with him) came to the province of Baghdad, he went to Hazrat Abu Mas'ud Ansari and greeted him. Hazrat Abu Mas'ud asked, "What is the condition of your sword, O Abu Abdullah?" He replied, "Hazrat Uthman has appointed me as the governor of this province." He said, "O Abu Abdullah, do you fear that this is a tribulation, while the people have expelled Hazrat Sa'id bin Aas?" Hazrat Hudhaifa (may Allah be pleased with him) said to him, "Do you not know your religion, O Abu Mas'ud?" He replied, "Why not?" Then Hazrat Hudhaifa (may Allah be pleased with him) said, "Indeed, the tribulation will not harm you as long as you recognize your religion. The tribulation is only when truth and falsehood become confused for you, and you do not know which of the two to follow. That is the tribulation."
