Ka'b bin Ujra

Ka'b ibn Ujra (RA) was a companion of the Prophet ﷺ primarily known in hadith literature for a specific narration linked to a notable event during the expedition to al-Hudaybiyyah. When the Muslims set out for Mecca in 6 AH and were halted, Ka'b (RA) fell ill with head lice tormenting him severely. The Prophet ﷺ noticed his suffering and inquired, then Allah revealed the Quranic verse (al-Baqarah 2:196) regarding the fidyah (expiation) for those who shave their heads while in a state of ihram due to illness or necessity. The options are: three days of fasting, feeding six poor people, or sacrificing an animal. This event and the resulting ruling are directly tied to Ka'b's name, and the hadith is referred to among scholars as 'hadith Ka'b ibn Ujra.' He narrated from the Prophet ﷺ and lived in Medina and later Kufa. He also participated in significant military campaigns. His narrations, while not as numerous as those of the great prolific companions, are considered authentic and appear in Sahih al-Bukhari, Sahih Muslim, and the Sunan collections. He is remembered particularly for his connection to this important ruling in the law of Hajj and as one of the companions who witnessed the revelation of a Quranic verse relating to a personal situation he had experienced.
