Sunan Abi Dawud, Hadith 3752 ⓘ
Narrated Salman al-Farsi: I read in the Torah that the blessing of food consists in ablution before it. So I mentioned it to the Prophet. He said: The blessing of food consists in ablution before it and ablution after it. Sufyan disapproved of performing ablution before taking food. Abu Dawud said: It is weak.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا قَيْسٌ، عَنْ أَبِي هَاشِمٍ، عَنْ زَاذَانَ، عَنْ سَلْمَانَ، قَالَ قَرَأْتُ فِي التَّوْرَاةِ أَنَّ بَرَكَةَ الطَّعَامِ الْوُضُوءُ قَبْلَهُ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ صلى الله عليه وسلم فَقَالَ " بَرَكَةُ الطَّعَامِ الْوُضُوءُ قَبْلَهُ وَالْوُضُوءُ بَعْدَهُ " . وَكَانَ سُفْيَانُ يَكْرَهُ الْوُضُوءَ قَبْلَ الطَّعَامِ . قَالَ أَبُو دَاوُدَ وَهُوَ ضَعِيفٌ .
