(17) باب صَدَقَةِ الزُّرُوعِ وَالثِّمَارِ
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.' "
