Is the sale of oils (Adhān) in their containers permissible when the seller has observed the containers?

Primary text

The sale of oils in their containers is permissible if the seller has observed the contents as a whole. This ruling applies because the constituent parts do not differ, rendering it analogous to the sale of a pile of grain (Sabra). This ruling extends to honey, molasses (Dibs), vinegar, and all other non-varying liquids. It is also valid if the sale is stipulated as a fixed price per unit weight (e.g., every ratl for one dirham), if a specific quantity (ratl) is sold, or if a known quantity exceeding the actual amount is sold. Furthermore, selling a fractional share (musha') or parts of the oil, or selling the oil along with the container for a known price, is permissible.
