It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna al-Abbas (may Allah be pleased with him): "O uncle, the world will not come to an end until, at the end of time, at the ending of their dynasty, a man from your descendants becomes ruler, and he will be the eighteenth. In his time there will be a blind and deaf tribulation, in which out of every ten thousand, nine thousand nine hundred will be killed; only very few will be saved from it, and their fighting will take place at a location in Iraq."
The narrator relates that (on hearing this) Sayyiduna al-Abbas (may Allah be pleased with him) began to weep, so the Messenger of Allah (peace and blessings be upon him) said to him: "What has made you weep? Indeed, they will be the worst of my Ummah; they will pass out of the religion as an arrow passes through the game; they will seek the world and will have no concern for the Hereafter."
This hadith is not narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) except with this chain, and Ahmad bin Muhammad al-Yamami is alone in narrating it.
