Kaab in Islam
Kaʿb ibn Malik, a poet of the Ansar, was one of the three Companions who stayed behind from the expedition of Tabuk: he refused to make excuses and waited fifty days for Allah’s forgiveness, revealed in verse 9:118. He told this story of repentance himself (al-Bukhari 4418). The expiation owed by a pilgrim who shaves his head because of illness (2:196) was revealed about Kaʿb ibn ʿUjra (al-Bukhari 4517).

But if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and do not find water, then seek clean earth and wipe over your faces and hands with it. Allāh does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.
