It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when these verses, from "O mankind, fear your Lord" to "but the punishment of Allah is severe," were revealed to the Prophet (peace and blessings be upon him) during a journey, he (peace and blessings be upon him) recited them in a loud voice, until his Companions (may Allah be pleased with them), hearing his voice, gathered around him. Then he (peace and blessings be upon him) asked: "Do you know what day this is? This is the day when Allah Almighty will say to Sayyiduna Adam (peace be upon him): 'Arise and send forth the contingent of Hell: out of every thousand, nine hundred and ninety-nine to Hell and only one to Paradise.'" This weighed very heavily on the Muslims, so the Prophet (peace and blessings be upon him), consoling them, said: "Keep to what is right, take the middle course, and receive glad tidings. By the One in whose Hand is my soul! Compared with the rest of mankind you are just like a mole on the side of a camel, or a mark of coloured hair on the foreleg of an animal. And with you are two creations (groups) that increase whatever they are among: Ya'juj and Ma'juj (Gog and Magog), and those of the disbelievers among the jinn and mankind who have perished."
