Ka'b ibn Ujrah

Ka'b ibn Ujrah al-Ansari, may Allah be pleased with him, was a companion of the Prophet ﷺ who embraced Islam and settled in Medina. He is best known as the narrator of two foundational hadiths: the fidyah (ransom) for a pilgrim who must shave his head during ihram due to illness or lice, where the Prophet ﷺ gave him personal instruction, and the complete form of the Abrahamic prayer upon the Prophet ﷺ that forms the conclusion of the tashahhud recited in every prayer. The latter narration is regarded by jurists of all four madhabs as the authoritative source for the obligatory or recommended prayers upon the Prophet ﷺ in salah. Ka'b later moved to Kufa in Iraq, where he continued transmitting knowledge to the Tabi'in. He was held in high regard among the companions for his piety and his direct transmission of practical rulings from the Prophet ﷺ. His narrations are preserved in Sahih al-Bukhari, Sahih Muslim, and all the major Sunan collections. The hadith on fidyah is a cornerstone of the chapter on Hajj in every classical fiqh manual, and the Abrahamic prayer he transmitted is recited by Muslims in every prayer performed to this day.
