It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that once we were on a journey with the Prophet (peace and blessings be upon him). The companions (may Allah be pleased with them) were walking at different speeds. The Prophet (peace and blessings be upon him) recited these two verses in a loud voice, then this verse was revealed: "O people! Fear your Lord, surely the earthquake of the Hour is a tremendous thing." When the companions (may Allah be pleased with them) heard its sound, they brought their mounts closer and gathered around the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) asked, "Do you know what day that will be?" That will be the day when Allah, the Exalted, will call out to Hazrat Adam (peace be upon him) and say, "O Adam! Bring forth the portion of Hell." He will ask, "What is the portion of Hell?" It will be said, "From every thousand, take out nine hundred and ninety-nine for Hell." Upon hearing this, the companions (may Allah be pleased with them) began to weep. The Prophet (peace and blessings be upon him) said, "Continue to do good deeds and rejoice. You will be with two such groups that, whenever they join something, they increase its number, that is, Gog and Magog, and those destroyed from among the children of Adam, and the offspring of Satan." At this, the state of the companions (may Allah be pleased with them) changed. The Prophet (peace and blessings be upon him) again said, "Continue to do good deeds and rejoice. By Him in Whose hand is the life of Muhammad (peace and blessings be upon him), among all the nations, you will be like a mark on the side of a camel."
