Allah's Messenger (ﷺ) 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 stature), sixty cubits tall."
Sahih al-Bukhari Book 60, Hadith 2
← Previous Hadith The Prophet (ﷺ) said, "Allah created Adam, making him 60 cubits tall. When He created him, He said to him, "Go and greet that group of angels, and listen to their reply, for it will be your greeting (salutation) and the greeting (salutations of your offspring." So, Adam said (to the angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels said, "As-salamu Alaika wa Rahmatu-l-lahi" (i.e. Peace and Allah's Mercy be upon you). Thus the angels added to Adam's salutation the expression, 'Wa Rahmatu-l-lahi,' Any person who will enter Paradise will resemble Adam (in appearance and figure). People have been decreasing in stature since Adam's creation.

Sahih al-Bukhari Book 60, Hadith 1 Next Hadith → Um Salama said, "Um Sulaim said, 'O Allah's Messenger (ﷺ)! Allah does not refrain from saying the truth! Is it obligatory for a woman to take a bath after she gets nocturnal discharge?' He said, 'Yes, if she notices the water (i.e. discharge).' Um Salama smiled and said, 'Does a woman get discharge?' Allah's Apostle said. 'Then why does a child resemble (its mother)?"
