Jami` at-Tirmidhi 2537

Abu Hurairah narrated that the Messenger of Allah (s.a.w) said:"The first batch to enter Paradise will appear like the moon of a night that it is full, they do not spit, nor do their noses run, nor do they defecate. Their vessels are of gold, their combs are of silver and gold, their perfume is of Aluwwah, and their sweat is musk. Each one of them has two wives, so beautiful that the marrow of their shins can be seen through the flesh. There is no differing among them nor mutual hatred, and their hearts are like the heart of one man, and they glorify Allah morning and evening
