It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the news of the death of the Negus (al-Najashi) came, the Messenger of Allah (peace and blessings be upon him) said: "Offer the funeral prayer for him." The Companions (may Allah be pleased with them) said: "O Messenger of Allah, will you offer the funeral prayer for an Abyssinian?" So Allah Almighty revealed this verse: "And indeed, among the People of the Book are some who believe in Allah and in what has been revealed to you."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Humayd except Abu Bakr bin Ayyash and Mu'tamir bin Sulayman."
