Khall (vinegar: ruling, purity and sale)

الخل

Vinegar is valuable clean property, lawful to eat and to trade, and it may come from wine; the report says "vinegar is a good condiment". ¹² Turning wine into vinegar: if it turns naturally, it is lawful by agreement; by treatment (onion, salt, fire), the Shafiis, Hanbalis and one Maliki report forbid it, citing the report of Abu Talha on whether to pour it out, while the Hanafis and the preferred Maliki view allow it. ²³ Eating and drinking vinegar is lawful by agreement; the worms in it may be eaten with it, though eating them alone is forbidden. ³ Purity by vinegar: it may not replace water for lesser or greater impurity, since it is not pure water; most jurists do not clean impurity with it, while Abu Hanifa, Abu Yusuf and one Hanbali view allow it, on the report of Aisha rubbing blood with the nail. ³⁴ Sale of vinegar: the same kind may not be exchanged unequally or deferred, being a usury good; the Hanafis, Shafiis and Hanbalis in the sounder view allow exchange of different kinds unequally; the Hanbalis except grape vinegar against raisin vinegar; the Malikis count all vinegars as one kind. ⁴⁵⁵⁶ Seizure and destruction: whoever seizes or destroys vinegar must pay; if a usurper turns seized wine into vinegar, it returns to the owner by the Hanafis, Malikis, Hanbalis and the sounder Shafii view; if the usurper treats it with valuable salt, Abu Hanifa gives the vinegar to him, while Abu Yusuf and Muhammad give it to the owner. ⁶ Seizing juice that turned to wine: most jurists require the like; if it turned to vinegar after fermentation, the Hanbalis and the sounder Shafii view return it with the loss, and the Malikis let the owner take juice of the like or the vinegar. ⁶⁷
