On the authority of Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "The first group to enter Paradise will have faces like the moon on the night of the full moon. They will not spit, nor clear their noses, nor relieve themselves. Their vessels therein are of gold, their combs are of gold and silver, their incense burners are of aloeswood, and their perspiration is musk. Each one of them will have two wives, the marrow of whose shanks will be visible from beneath the flesh due to their beauty. There will be no discord among them, nor hatred; their hearts will be as one heart, glorifying Allah morning and evening." (1)

This is an authentic hadith.

Al-aluwwah: it is the aloeswood.

2713 - Suwayd ibn Nasr narrated to us, saying: 'Abdullah informed us, saying: Ibn Lahi'ah informed us, on the authority of Yazid ibn Abi Habib, on the authority of Dawud ibn 'Amir ibn Sa'd ibn Abi Waqqas, on the authority of his father, on the authority of his grandfather, on the authority of the Prophet, peace and blessings be upon him, who said: "If something of what a fingernail could carry of what is in Paradise were to appear, it would adorn with splendor all that lies between the horizons of the heavens and the earth. And if a man of the people of Paradise were to look out and his bracelets were to appear, they would blot out the light of the sun just as the sun blots out the light of the stars." (2)
