Zakat on Crops: Working Out the Rate When Rain and Pumps Are Mixed

The case every general explanation skips

Zakat on crops is always presented as two rates: a tenth where irrigation costs nothing, half a tenth where it does. Then the actual farmer is left without an answer, because he falls in neither — he relies on rain for months, then runs pumps through the dry spell.

This article is about that middle case, and how to work it out precisely.

First: has your harvest reached the nisab?

The threshold is five wasqs. A wasq is sixty sa', so five wasqs are three hundred sa'.

Valuing the Prophetic sa' at roughly 2.04–2.176 kg, the nisab comes to about 612–653 kg of wheat, barley or dates. The range reflects differing estimates of the sa' and the density of the grain; the cautious course is to use the lower figure.

Note: that is five wasqs combined, not one. Confusing the two multiplies the threshold fivefold and exempts a farmer who in fact owes.

Unlike zakat on money, there is no hawl for crops — it falls due on harvest day: "and give its due on the day of its harvest."

Second: how much? The rate follows the water

Irrigation	Rate	Reasoning
Rain, springs or rivers — no cost	10%	No burden on the farmer
Wells, pumps or purchased water	5%	Cost lightens the obligation
Both equally	7.5%	Half of each ruling
One predominates	Follows the dominant	The lesser follows the greater

Where it is unclear, the dominant source governs; where they are genuinely equal, 7.5%.

Third: determining which dominates

Dominance is not counted in waterings but in what sustained the crop through its growth. The closest workable measure available to a farmer is the number of days the crop depended on each source across the growing season.

This is a considered estimate, not an exact computation, and the farmer is trusted with it. Where genuinely in doubt, the safer course is the higher rate — zakat is an established right of the poor, not a figure to be trimmed.

A worked example

Abu Salim grows wheat and harvests 4,200 kg over a 140-day growing season:

• Rain sustained the crop for 95 days
• The well pump ran for 45 days

Step	Working	Result
Nisab	4,200 kg against 653 kg	Exceeded
Share from rain	95 ÷ 140	68%
Ruling	Rain predominates	A tenth — 10%
Due	4,200 × 10%	420 kg

Reverse the figures — 45 days of rain against 95 of pumping — and cost predominates, making it 5%, or 210 kg. The dominance judgement doubles or halves the obligation, which makes it the single most consequential number in the whole calculation.

Are growing costs deducted?

Jurists differ. The majority hold that zakat is on the gross harvest, without deducting seed, labour or fuel — because the rate was already halved in consideration of cost, and the same allowance should not be counted twice.

Some contemporary scholars permit deducting direct expenses and paying on the net, given the cost of modern farming.

This site does not deduct costs, following the majority and because not deducting discharges the obligation more surely. A reader following the other view should subtract expenses before applying the rate.

Which crops are covered?

The majority position covers staple foods that can be stored: wheat, barley, rice, maize, dates and raisins.

Abu Hanifa held that zakat is due on everything deliberately produced from the land, including vegetables and fruit.

So a grower of tomatoes or cucumbers is governed by which school they follow — and both positions are held by recognised authority.

Frequently asked questions

Do I pay in crop or in cash after selling?

The default is to pay in kind — wheat from wheat, dates from dates. Many contemporary scholars permit cash where it serves the recipient better, which is Abu Hanifa's position. Value it at the harvest-day price, not the day you sold.

I harvest twice a year. Do both count?

Yes. There is no hawl for crops, so each harvest stands on its own. On the majority view the nisab is assessed per harvest, so a harvest falling below the threshold carries no zakat.

The land is rented. Who pays?

Zakat falls on whoever owns the crop, not the landowner, since it attaches to the produce rather than the asset. The rent is a debt on the tenant and is not deducted from the harvest on the majority view, consistent with not deducting costs.

What if pests destroyed part of the crop?

Zakat is due only on what survives; what perished before harvest carries none. If the surviving amount falls below the nisab, no zakat is owed. What is lost after harvest, once payment was possible, does not remove an obligation that had already settled.
