'Atiyyah Al-'Awfi narrated from Abu Sa'eed Al-Khudri,that The Messenger of Allah (s.a.w) said:
"Whichever believer feeds a hungry believer , Allah feeds him from the fruits of Paradise on the Day of Resurrection. Whichever believer gives drink to a thirsty believer, Allah gives him to drink from the 'sealed nectar' on the Day of Resurrection. Whichever believer clothes a naked believer, Allah clothes him from the green garments of Paradise." (DE)
