Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "On the Day of Resurrection, people will sweat so much that it will spread over the earth and will go down seventy cubits into the ground (the earth will become wet to that depth), and people will be submerged in their sweat up to their mouths, or half of their ears."
