كتاب الزكاة
Read the English translation first, with the original Arabic directly underneath.
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."
فِيمَا سَقَتِ السَّمَاءُ وَالأَنْهَارُ وَالْعُيُونُ أَوْ كَانَ بَعْلاً الْعُشْرُ وَمَا سُقِيَ بِالسَّوَانِي وَالنَّضْحِ نِصْفُ الْعُشْرِ
