It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: On the Day of Resurrection, people will be gathered in three groups: one group will be those who walk on foot, one group will be those who ride, and one group will be those who walk on their faces. The companions (may Allah be pleased with them) asked, "O Messenger of Allah! How will people walk on their faces?" He replied: The One who makes them walk on their feet is surely able to make them walk on their faces as well. Therefore, they should protect their faces from every slippery place and thorn.
