Ibn Majah

Lexical Explanation:
«اَوَاقٍ» has tanween on it. After the letter qaf, both the form with a shadda on ya and the lighter form are permissible; it is the plural of "uqiyah." On the hamzah of "uqiyah" there is a dammah, and the ya has a shadda. One uqiyah contains forty dirhams, and thus five uqiyahs are two hundred dirhams. According to modern weight measurements, two hundred dirhams weigh 615 grams.

«اَلْوَرِقِ» has a fathah on the waw and a kasrah under the ra, and the ra is also read as sakin. Its meaning is "silver."

«ذَوْدِ» has a fathah on the dhal and a sukun on the waw; it means "camel." This is a collective noun, and it includes both masculine and feminine, as well as few and many. For this reason, attributing the khums (one-fifth) to it is permissible.

«اَوْسُقِ» has a fathah on the hamzah, a sukun on the waw, and a dammah on the sin. It is the plural of «وسق». For «وسق», both fathah and kasrah on the waw are permissible. One wasq (wasq) is sixty sa’ (sa’), and five wasq are three hundred sa’. And you know that one sa’ contains four mudd, and one mudd is equal to one and one-third ratl. Also, according to modern measurements, one sa’ is approximately two and a half kilograms.

« اَوْسَاقٍ» is the plural of «وسق», like «اوسق».

«حَبَّ» has a fathah on the ha and a shadda on the ba. It means seed, kernel, wheat seed, barley, lentils, etc.

The word «دُونَ» in all four places is in the meaning of «اَقَلُّ», i.e., zakat is not obligatory on less than the mentioned amounts of these items.

Benefit:
In this hadith, the nisab (minimum threshold) for silver is stated as five uqiyah, while in the previous hadith it is two hundred dirhams. There is no contradiction or difference between these two hadiths, because one uqiyah contains forty dirhams, and five uqiyahs make two hundred dirhams, so there is no contradiction.

Three hundred sa’ of Hijazi measure, according to the English weights prevalent in our country, is approximately twenty man (a local weight unit). One wasq contains sixty sa’, which is equal to four man. Thus, according to our local calculation, there is no zakat on less than twenty man of grain. However, the Hanafis, considering the generality of the Book of Allah and the hadith, have given the fatwa that zakat is obligatory on grain and dates, even if it is one man or less. But the first opinion is more correct, because when the Prophet sallallahu alayhi wa sallam himself specified the weight, then we should act upon that. There is no permission to add or subtract from it on our own. Zakat is obligatory on every type of produce that can be stored for a year, such as: wheat, rice, barley, millet, corn, mash beans, mung beans, and chickpeas, etc.
