It is narrated from Hazrat Abu Umamah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: On the Day of Resurrection, the sun will come as close as the distance of one mile, and its heat will increase so much that brains will boil like pots, and all people will be submerged in sweat according to their sins. Thus, some will have sweat up to their ankles, some up to their shins, some up to the middle of their bodies, and some will have a bridle of sweat in their mouths.
