Sunan Abi Dawud, Hadith 1677 ⓘ
Narrated Sa'd ibn Ubadah: Sa'd asked: Messenger of Allah, Umm Sa'd has died; what form of sadaqah is best? He replied: Water (is best). He dug a well and said: It is for Umm Sa'd.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنْ رَجُلٍ، عَنْ سَعْدِ بْنِ عُبَادَةَ، أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ إِنَّ أُمَّ سَعْدٍ مَاتَتْ فَأَىُّ الصَّدَقَةِ أَفْضَلُ قَالَ " الْمَاءُ " . قَالَ فَحَفَرَ بِئْرًا وَقَالَ هَذِهِ لأُمِّ سَعْدٍ .
