It is narrated from Khalifa bin Saad that I saw Hazrat Uthman walking on one of the streets of Madinah, and he was saying: "Continue to enjoin good and forbid evil before your wicked people are set over you. Then your best people will pray against them, but their prayers will not be accepted. Then hardship will weigh heavily upon them, and they will be seized by their arms." Then he said: "I will not die until I am overtaken by the leadership of young boys."
