Hadith 5:284
Muhammad ibn Bakr narrated to us, from Ibn Jurayj, who said: I said to ‘Ata regarding what is irrigated by *kaza’im* (underground water channels) of date palms, grapes, or grain: "Is there a tenth (zakat)?" He said: "The tenth."
حدثنا محمد بن بكر عن بن جريج قال قلت لعطاء فيما يسقى بالكظائم من نخل أو عنب أو حب قال العشر
