Glossary of the ḥadith:
– nasīʾah: written with a hamzah after the yāʾ, patterned like karīmah; if the hamzah is assimilated, it follows the pattern of ʿaṭiyyah. Grammatically, it functions as a circumstantial accusative. Linguistically nasīʾah means deferment; here it refers to selling one animal for another while postponing delivery beyond the moment of sale.
