zakat has been deducted from them. According to Ashhab’s position regarding the two separately acquired sums, however, he pays zakat on the three wasqs.
If he sows the second kind before harvesting the first, then sows the third after harvesting the second but before harvesting the first—for some pulses ripen early and others late—he combines the first with both the second and the third, but does not combine the second with the third, following the same reasoning. If he gathers three wasqs from the second crop, he waits until he harvests the first. If the first yields two wasqs or more, and the three wasqs remain in his possession unspent, then, according to Ibn al-Qāsim, he pays zakat on the three wasqs together with these two wasqs. If he then harvests the third crop, and its yield, combined with what remains of the two wasqs harvested from the first after zakat has been deducted from them, reaches the threshold, he pays zakat only on what he harvested from the third. He does not pay zakat again on what remains of the two wasqs, since he has already paid zakat on them together with what he harvested from the second. According to Ashhab, however, he pays zakat on what he harvests from the third if it amounts to three wasqs or more, whether the two wasqs remain in his possession or he has already spent them, as explained above.
Section
The same reasoning applies to zakat on mines. What a mine produces after its yield has ceased is not combined with what it produced previously, just as grain produced by a plot of land is not combined with what it produced previously. Likewise, the yield of one mine is not combined with that of another if it is obtained after the first mine has ceased yielding. It is combined with it only if obtained before the first mine ceases yielding. Similarly, the crop of one plot is not combined with that of another if one was sown after the other was harvested; they are combined only if it was sown before the crop of the other plot was harvested.
Section
If a man has several mines and works the first until it yields, then works the second and obtains a yield before the first ceases yielding, then works the third and obtains a yield before the first and second cease yielding, he combines their yields, however numerous the mines may be, provided that they follow this pattern and sequence. If he works the first and obtains a yield, then works the second and obtains a yield before the first ceases yielding, and both continue to yield,
