It was narrated from Salim, from his father, that the Messenger of Allah said:

"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 and artificial means, one half of one-tenth."

أَخْبَرَنَا هَارُونُ بْنُ سَعِيدِ بْنِ الْهَيْثَمِ أَبُو جَعْفَرٍ الأَيْلِيُّ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " فِيمَا سَقَتِ السَّمَاءُ وَالأَنْهَارُ وَالْعُيُونُ أَوْ كَانَ بَعْلاً الْعُشْرُ وَمَا سُقِيَ بِالسَّوَانِي وَالنَّضْحِ نِصْفُ الْعُشْرِ " .
