A man says that once we collected some things to go and give them to Hazrat Abu Dharr (may Allah be pleased with him). So we reached "Rabadha" and started searching for him, but he was not found there. Someone informed us that he had sought permission to go for Hajj, which was granted to him. So we reached Mina. While we were sitting with him, someone came and informed him that Hazrat Uthman Ghani (may Allah be pleased with him) had led four rak‘ahs of prayer in Mina. This weighed heavily on Hazrat Abu Dharr (may Allah be pleased with him), and he said some harsh words, saying: "I have prayed with the Prophet Muhammad (peace and blessings be upon him), and he prayed two rak‘ahs, and I have also prayed in the same way with Hazrat Abu Bakr and Umar (may Allah be pleased with them)." Then Hazrat Abu Dharr (may Allah be pleased with him) stood up and prayed four rak‘ahs. Someone said to him: "Earlier you criticized the action of the Commander of the Faithful, but now you are doing the same thing yourself." He replied: "To differ (with the leader) is even more severe." The Prophet Muhammad (peace and blessings be upon him) once addressed us in a sermon and said: "After me, a king will come; do not humiliate him. Whoever wishes to humiliate him, it is as if he has removed the rope of Islam from his own neck, and his repentance will not be accepted until he closes the hole which he has opened, but he will not do so. Then if he returns, he will be among those who honor (the leader)." The Prophet Muhammad (peace and blessings be upon him) also commanded that we should not be overcome regarding three things: continue to enjoin good, continue to forbid evil, and continue to teach people the Sunnahs.
