Hadith 614

Salim bin ’Abdullah narrated on the authority of his father (RAA) that the Messenger of Allah (P.B.U.H.) said, “A tithe is due as Zakah, on every plant watered by heaven (rain water), springs, or underground water (i.e. watered without effort).While half a tithe is paid on what is watered by irrigation (i.e. machines are used).” Related by Al-Bukhari. Abu Dawud added in his narration, “When it is watered by underground water (close to the surface and keeping the land wet), a tithe is paid, but half a tithe is paid when the land is watered by wheels or animals.”
