Musannaf Ibn Abi Shaybah 10356 — Crops watered by flowing water

It is narrated from Salih Abu al-Khalil that the Prophet (peace and blessings be upon him) established the practice that on land watered by rain, or by a flowing spring, or by running stream water, or land that needs no watering and draws its water from the moisture of the soil, on all of these there is a full tenth; and on land irrigated by rope (and bucket) there is half a tenth.
