Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) said: The Truthful and Trusted (peace and blessings be upon him) told me: "On the Day of Gathering, people will be assembled in three groups. One group will be those who are eating and dressed, the second group will be those who are walking and running, and the third group will be those whom the angels will be dragging and the fire will be gathering them from behind." He said: We have recognized them, but what is the sign of those who will be walking and running? So the Prophet (peace and blessings be upon him) said: "Calamity will come upon the riding animals so that there will be no riding animal left, to the extent that a man will give a garden in exchange for an old riding animal with a saddle, but even then he will not get it."
