What is the ruling on giving Zakat from 1000 sacks of wheat and barley by deducting 100 sacks as rent for the harvester, and then giving 100 sacks as Zakat? And is there Zakat due on the owner of the harvester for what he takes as rent? And are cultivation expenses deducted before giving Zakat?

The nisab (minimum threshold) for crops and fruits is five awsuq (plural of wasq), with one wasq equaling 60 sa's. Zakat is obligatory on them at one-tenth if irrigated by rain or flowing water, and at one-half of one-tenth if irrigated by machinery or if transporting water involves expense. The majority of scholars hold that the cost of cultivation is not deducted from the produce, and zakat is obligatory on the entire yield. However, some scholars are of the opinion that the cost is deducted from the principal of the harvest, and zakat is then paid on the remainder if it reaches the nisab. This latter opinion is the preferred one. As for the owner of the harvesting machine, zakat is not obligatory on what he receives as payment for his work.
