Abu Hurayrah (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The first group to enter Paradise will look like the moon when it is full. They will not spit or blow their noses or defecate. Their vessels will be of gold, their combs will be of gold and silver, their incense burners will be of aloes-wood and their sweat will be musk. Each one of them will have two wives whose marrow can be seen through their flesh because of their beauty, and there will be no disputes or grudges among them. Their hearts will be as one and they will glorify Allaah morning and evening.” Bukhari and Muslim

Rasulullah said “The people of Paradise are 120 rows, of which eighty are from this ummah and the other forty from all the other nations.” Reported by al-Tirmidhi, and it's Hasan

And I know another hadeeth in which it says that the Poor people will enter Paradise 500 or 5000 years before the rich people.......but I cannot remember now who will be the first?

I will have to do more research later Insha'allah, right now I have to go for Jumu'ah!!!! Wassalamu'alaikum
