It is narrated from Hazrat Jabir bin Samurah, may Allah be pleased with him, that I heard the Prophet, peace and blessings be upon him, say: "There will be twelve caliphs after me, all of them will be from the Quraysh." After saying this, the Prophet, peace and blessings be upon him, went to his house. Then the people of Quraysh came to him and asked, "What will happen after that?" The Prophet, peace and blessings be upon him, said: "After that, there will be widespread killing and chaos."
