Sahih Al Bukhari Vol 6.402:
Narrated `Abdullah bin Qais: Allah's Apostle said, "In Paradise there is a pavilion made of a single hollow pearl sixty miles wide, in each corner of which there are wives who will not see those in the other corners; and the believers will visit and enjoy them. And there are two gardens, the utensils and contents of which are made of silver; and two other gardens, the utensils and contents of which are made of so−and−so (i.e. gold) and nothing will prevent the people staying in the Garden of Eden from seeing their Lord except the curtain of Majesty over His Face."
Sahih Al Bukhari Vol 4.544:
Narrated Abu Huraira: Allah's Apostle said, "The first group of people who will enter Paradise, will be glittering like the full moon and those who will follow them, will glitter like the most brilliant star in the sky. They will not urinate, relieve nature, spit, or have any nasal secretions. Their combs will be of gold, and their sweat will smell like musk. The aloes−wood will be used in their centers. Their wives will be houris. All of them will look alike and will resemble their father Adam (in statute), sixty cubits tall."
(This means that the first group can only be men since they have wives)
Sahih Muslim Bk 1, Number 0172:
Abu Dharr reported,: I came to the Apostle (may peace be upon him ) and he was asleep with a white mantle over him. I again came, he was still asleep, I came again and he had awakened. I sat by his side and (the Holy Prophet) observed: There is none among the bondsmen who affirmed his faith in La illaha ill−Allah there is no God but Allah) and died in this state and did not enter Paradise. I (Abu Dharr) said: Even if he committed adultery and theft? He (the Holy Prophet) replied: (Yes) even though he committed adultery and theft. I (again said): Even if he committed adultery and theft? He replied: (Yes) even though he committed adultery and theft. (Th Holy Prophet repeated it three times) and said for the fourth time: In defiance of Abu Dharr. Abu Dharr then went out and he repeated (these words): In defiance of Abu Dharr.
Sahih Al Bukhari Vol 9.579:
Narrated Abu Dharr: The Prophet said, Gabriel came to me and gave me the glad tidings that anyone who died without
worshipping anything besides Allah, would enter Paradise. I asked (Gabriel), 'Even if he committed theft, and even if he committed illegal sexual intercourse?' He said, '(Yes), even if he committed theft, and even if he Committed illegal sexual intercourse."
