Nafi' narrates from Ibn Umar (may Allah be pleased with them both) that whoever swears an emphatic oath and then breaks it must free a slave or clothe ten poor persons; and whoever swears an oath that is not emphatic must feed ten poor persons, one mudd of wheat for each poor person; and whoever does not find (the means) must fast three days.
(b) In the hadith of Ibn Bukayr it is that for an emphatic oath there is the freeing of a slave.
(c) There is no difference between the expiation of an emphatic oath and an ordinary one.
(28) Chapter: How much clothing suffices in the expiation? It is everything to which the name of clothing applies, such as a turban, trousers, a waist-wrapper, a head-covering and the like.
Everything to which (the word) clothing can apply, such as a turban, shalwar (trousers), a waist-wrapper or a small item, may be given in expiation.
Allah Almighty says: "or clothing them" [Surah al-Ma'idah: 89].
