حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ سَعِيدٍ، أَنَّ سَعْدًا، أَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ أَىُّ الصَّدَقَةِ أَعْجَبُ إِلَيْكَ قَالَ ‏"‏ الْمَاءُ ‏"‏ ‏.‏
Translation
Narrated Abu Sa'id (al-Khudri)

The Prophet (ﷺ) said: If any Muslim clothes a Muslim when he is naked, Allah will clothe him with some green garments of Paradise; if any Muslim feeds a Muslim when he is hungry, Allah will feed him with some of the fruits of Paradise; and if any Muslim gives a Muslim drink when he is thirsty, Allah will give him some of the pure wine which is sealed to drink.
