Sunan Abi Dawud, Hadith 1593 ⓘ
Narrated Jabir bin ‘Abdallah : The Messenger of Allah as saying A tenth is payable on what is watered by rivers and brooks or from underground moisture and a twentieth on what is watered by draught camels.
حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " فِيمَا سَقَتِ الأَنْهَارُ وَالْعُيُونُ الْعُشْرُ وَمَا سُقِيَ بِالسَّوَانِي فَفِيهِ نِصْفُ الْعُشْرِ " .
