حَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الْمِصْرِيُّ أَبُو جَعْفَرٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ " فِيمَا سَقَتِ السَّمَاءُ وَالأَنْهَارُ وَالْعُيُونُ أَوْ كَانَ بَعْلاً الْعُشْرُ وَفِيمَا سُقِيَ بِالسَّوَانِي نِصْفُ الْعُشْرِ " .
Salim narrated that: that his Father said: "I heard the Messenger of Allah say: 'For whatever is irrigated by the sky, rivers and springs, or draws up water from deep roots, one-tenth. For whatever is irrigated by animals (i.e. by artificial means) one half of one-tenth.' "
