The Messenger of Allah ﷺ said, "On what is watered by the sky, rivers, and springs, or what draws water from its own roots, a tenth is due. On what is watered by camels drawing water or by irrigation, half a tenth is due."
حدثنا هارون بن سعيد بن الهيثم الأيلي حدثنا عبد الله بن وهب أخبرني يونس بن يزيد عن ابن شهاب
قال رسول الله ﷺ فيما سقت السماء والأنهار والعيون أو كان بعلا العشر وفيما سقي بالسواني أو النضح نصف العشر
Bukhari narrated it in the Book of Zakat, chapter "The Tenth Due on What Is Watered by Rain and Flowing Water," hadith no. 1483, from the hadith of Abdullah bin Wahb, with this same chain.
