"The Negus [the Emperor of Ethiopia] gave the Prophet (Allah bless him and give him peace) a pair of plain black shoes, so he put them on, then performed the minor ritual ablution and wiped over them.”

"Dihya [a notable Companion of his] gave the Prophet (Allah bless him and give him peace) a pair of plain black shoes, so he wore them,"— and Isra’il said, on the authority of Jabir, on the authority of 'Amir: "[He also gave him] a gown, so he wore the shoes until they were perforated, without the Prophet (Allah bless him and give him peace) knowing whether or not they were made from the hide of a lawfully slaughtered animal.”
