It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Near the Day of Judgment, people will frequently be struck by fainting spells, to such an extent that a man will come to the people and ask, "Who among you fainted first this morning?" and they will reply, "So-and-so and so-and-so."
