Is there zakah in the straw collected after the harvest of grains?

The questioner : Shaykh, regarding the zakah on grains, such as wheat, for example, we know that for rain-fed crops it is ten percent. Now, when some grains are harvested, the straw resulting from this crop is worth more than the wheat itself. Is there zakah on the other things that are produced?

The Shaykh : Such as vegetables, whose material benefit is greater than that of the wheat, is there zakah on them?

The questioner: No.

The Shaykh : So the answer is no. That is, if the door of using opinion is opened, it will befall the Muslims what befell the Jews and the Christians.
