Musnad Ahmad

It is narrated from Hazrat Thawban (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty gathered the entire earth for me, so I saw its east and its west, and the rule of my Ummah will reach as far as the area that was gathered and shown to me. And I was given two treasures, the red and the white. And I requested my Lord for my Ummah that He not destroy it by a general famine, nor impose upon them an external enemy who would annihilate them utterly. So my Lord said: O Muhammad! When I make a decision, none can overturn it. I have accepted your supplication for your Ummah that I will not destroy them by a general famine, nor will I impose upon them an external enemy who will cause widespread slaughter among them, even if their enemies gather against them from all corners of the world, until they themselves begin to destroy one another. And I fear for my Ummah from misguided leaders. And when the sword is placed among my Ummah, it will not be lifted from them until the Day of Resurrection. And the Hour will not be established until some tribes of my Ummah join the polytheists, and until some tribes of my Ummah begin to worship idols. And soon there will appear thirty great liars in my Ummah, each of whom will claim to be a prophet, though I am the last prophet and there will be no prophet after me. And a group from my Ummah will always remain fighting for the truth, always prevailing, and no one who opposes them will be able to harm them until the command of Allah comes.
