کتاب الفتن · نُعیم بن حماد

The Banu Umayyads reigned for a hundred years, and the Banu Marwan had sixty-odd years of that. Their dominion will not go until they take it away with their own hands. They want to block it but they cannot do it. Every time they block it on one side, it collapses on the other. They begin with a mim and end with a mim. Their dominion will not go until a caliph of theirs is deposed and he is killed, and his lambs are killed, and the red-haired donkey of the peninsula kills Marwan, then their dominion is cut off and the wreaths are torn down at his hands.
