Vocabulary of the ḥadīth:
– qassi (with an open qāf and a doubled sīn, followed by a yāʾ): a type of striped cloth that contains silk, originally woven in a village near Damietta in Egypt. Al-ʿAynī noted that the village is now in ruins. Abū ʿUbayd said: “The ḥadīth scholars pronounce it qi ssi (with a kasrah on the qāf), whereas the people of Egypt open it with a fatḥah.”
– muʿaṣfar: the passive participle of the quadriliteral verb; it refers to fabric dyed with ʿuṣfur (safflower), a summer plant from the composite family whose tubular flowers yield a red dye used for silk and similar materials.
