Verily, the first group that will enter Paradise will look like the moon when it is full, and the next batch will be as radiant as the radiant star in the sky. Each one of them will marry two wives. The marrow of the bones of their shins will be seen through the flesh. None will be unmarried in Paradise.
This Hadith was recorded in the Two Sahihs.
Imam Ahmad recorded that Anas said that the Messenger of Allah said,
A morning or an evening journey in Allah's cause is better than the world and whatever is on its surface. And a place in Paradise as small as that occupied by the whip of one of you, is better than the world and whatever is on its surface. If one of the women of the people of Paradise looks directly at the earth, she will fill what is between Paradise and earth with a good scent and all of it will become delightful. Verily, the veil over her head is better than this life and all that is on its surface.
Al-Bukhari also collected a similar narration.
