"Let us conclude our talk on minting by mentioning the reality of the legislated dirham and dinar and the reality of their measures, because the dinar and the dirham are minted differently in their dimensions and weights in the different lands and provinces. The Revelation undertook to mention them and attached many judgements to them, for example, zakat, marriage, and hudud, etc., therefore within the Revelation they have to have a reality and a specific measure for assessment [of zakat, etc.] upon which its judgements may be based rather than on the non-shari' [dinars and dirhams which have become common]. Know that there is a consensus (ijma') since the beginning of Islam and the age of the Companions and the Followers that the dirham of the shari'ah is that of which ten weigh seven mithqals of gold, and an uqiyyah of which weighs forty dirhams, so that on the basis of this it [the weight of the dirham] is seven-tenths of [the weight of] a dinar. The weight of a mithqal of gold is seventy-two grains of barley, so that the dirham which is seven-tenths of it is fifty and two-fifths grains. All these measurements are firmly established by consensus."
