وكل شيء نص رسول الله صلى الله عليه وسلم على تحريم التفاضل فيه كيلا فهو مكيل أبدا وإن ترك الناس الكيل فيه مثل الحنطة والشعير والتمر والملح
Translation: Whatever the Messenger of Allah ﷺ treated as subject to the prohibition of unequal measured exchange remains makil even if people stop measuring it by volume, such as wheat, barley, dates and salt.
Where Prophetic texts establish volumetric measure for a commodity, the governing measure remains volumetric in this stated classical Hanafi rule, even if later merchants typically trade it by weight.
Quduri lists wheat, barley, dates and salt. Matching weights alone does not necessarily establish the required equal measured volume in same-genus exchange. Equal mass and equal volume are distinct propositions.
