chickpeas, fava beans, cow-peas, lentils, peas, garden peas, lupines, and every other grain that resembles what we have listed—anything people cultivate and eat, whether raw or cooked, processed or unprocessed, as a staple in time of need or otherwise, or merely as a relish, provided it is a cultivated grain. When the produce of a single type reaches five wasqs, a full tithe (one-tenth) is due if the land is rain-fed (baʿl) or watered by a river or natural spring; if it is irrigated by any other method, half of the tithe is owed instead.
One wasq equals sixty ṣāʿs, and a ṣāʿ is four mudds according to the mudd of the Prophet ﷺ, whose weight is one and one-third Baghdadi ratls, with a slight additional fraction. Thus, five wasqs amount to one thousand two hundred mudds by the Prophet’s mudd, equivalent by weight to one thousand six hundred Baghdadi ratls.
No variety is combined with another outside its own kind, and nothing is added across different genera. Mālik, however, combined all legumes, treating them as a single category for zakāt, even though in sales he regarded them as several distinct kinds. According to him, wheat, barley, and silt (husked barley) form one category for both commerce and zakāt, so their amounts are added together; millet is a separate kind; sorghum and rice another; ʿalas yet another; and no variety may be taken in payment for a different one. Where a crop is watered partly by rainfall and partly by irrigation so that the two methods are equal, three-quarters of the tithe is assessed.
Some hold that the lesser mode of watering follows the greater; others say that the zakāt is calculated by the method that sustained the crop to maturity, making the first subordinate to the second—all of these opinions are attributed to Mālik.
Whoever sells a standing crop after it has dried and the grain has hardened
