even if it were general, it would be necessary to prioritize the explicit specific [ruling] over it. The action and statement of Ma'mar cannot be opposed to the statement of the Prophet, peace and blessings be upon him, and their analogy is invalidated by gold and silver.

Section: Regarding wheat and its derivatives. Its derivatives are of two types: first, that which contains nothing other than it, such as flour and sawiq (parched grain porridge) (7). The second is that which contains other ingredients, such as bread, harisah (a porridge of wheat and meat), faludhaj (a gelatinous dessert) (8), starch, and their likes. It is not permissible to sell wheat for any of its derivatives. These are of three categories: first, sawiq; it is not permissible to sell it for wheat. This is the opinion of al-Shafi'i. It is narrated from Malik and Abu Thawr that such is permissible, whether equal or with disparity. Our position is that it is selling wheat for some of its components with disparity, which is not permissible, just like selling one makkuk (9) of wheat for two makkuks of flour. There is no way to achieve equality, because fire has affected one of them and not the other, so it resembles roasted [grain]. The second category is that which has other ingredients with it; therefore, it is not permissible to sell wheat for it either. The associates of Abu Hanifa said: That is permissible, based on the issue of the mudd of 'ajwah. We shall mention the evidence for that, if Allah the Almighty wills. The third category is flour; it is not permissible to sell wheat for it according to the correct opinion. This is the school of Sa'id ibn al-Musayyib, al-Hasan, al-Hakam, Hammad, al-Thawri, Abu Hanifa, and Makhul. This is the well-known position of al-Shafi'i. From Ahmad, there is another narration that it is permissible. This is the opinion of Rabi'ah and Malik, and it was narrated from al-Nakha'i, Qatadah, Ibn Shubruma, Ishaq, and Abu Thawr; because flour is the very essence of wheat, only its parts have been broken down, so it is permissible to sell some of it for some of it, like broken wheat (10) for whole wheat. According to this, wheat is only sold for flour by weight, because its parts have separated through grinding and dispersed, so it occupies a large space in the measuring container, while wheat occupies a small space, and weighing balances between them. Ishaq held this view. Our position is that selling wheat for flour is a sale of wheat for its own genus
