Is estimating the zakah of stored grain by weight or measure sufficient?

Question : He says, in response to the last question: The date sellers, Honorable Shaykh, take the zakah by weight, not by measure. This is my question; I hope you will clarify the zakah by weight or by measure?

Answer : What matters, my brothers, is that as long as they give you dirhams, whether they estimate it by measure or by weight, they will give you the value of what came into their possession. If they give you the value, you pay out two and a half percent and it is done. The issue is clear; there is no problem in it. They lose a little, right? What do they take it as? As what? Not as the value. He tells you the kilo is two riyals, and when it reaches a thousand kilos, that is two thousand riyals. Take two and a half percent from the two thousand. Do they deduct it? It is sufficient. They calculate it as something they spend, if Allah wills, on expenses. The question is not about this. If the question were whether it is sufficient for them to take it, we would say: Yes, it is sufficient.
