Musannaf Ibn Abi Shaybah 40415 — Reports on the tribulation

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that he said: A people will come to you from the direction of the east, broad-faced and small-eyed, as if their eyes had been made by boring holes in rock, and their faces will be like swollen shields, until they tie their horses on the bank of the Euphrates.
