On The Excellence Of Supplying Drinking Water
Sunan Abi Dawud
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 " .
Sa’id reported Sa’d came to the Prophet (SWAS) and asked him Which sadaqah do you like most? He replied Water.
