to a man, “Harvest this crop in return for one-third of it,” and he harvests it for that one-third, then no zakah is due on the third, because he did not own it when zakah became obligatory; rather, he acquired ownership of it afterward.

First: reaching the nisab.
Second: that the nisab be owned by him at the time zakah becomes due.
His statement, “Nor is zakah due on what he gathers from that which is freely available, such as butm, zaʿbal, and cottonseed”: “that which is freely available” refers to what grows in the open land by Allah’s bringing it forth. If a person gathers a large amount of it, no zakah is due on it, because at the time zakah becomes obligatory it is not his property. For freely available things—such as grass and the like—do not become a person’s property until he takes possession of them.
Zaʿbal, with the metrical pattern of Jaʿfar, is mountain barley.
As for “cottonseed,” our shaykhs say that it is the ear of grass; and grass is called among us riblah.
