Musa bin Ali narrated from his father, he said: I set out for Hajj, so Salim bin 'Itr, who was the judge of the people of Egypt during the rule of 'Amr bin al-'As (may Allah be pleased with him) and after him, advised me to convey his greetings to Abu Hurairah (may Allah be pleased with him), and he said: Yesterday I prayed for forgiveness for his father and mother. So when I met Abu Hurairah (may Allah be pleased with him) in Madinah, I conveyed the greetings to him, and he said: Yesterday I prayed for forgiveness for him and his family. Then he said: How did you leave Umm Khunur (Egypt)? Tell us about its condition. He said: The first corruption will arise in that land, then after that in Armenia. He narrated: I said to him: Did you hear this from the Messenger of Allah (peace and blessings be upon him)? He said: Then who else, Ka'b the one with two books?
