It was narrated from Ibn ‘Abbas that the Prophet (ﷺ) recited the Opening of the Book (Al-Fatihah) in the funeral prayer.
Sunan Ibn Majah Book 6, Hadith 63
← Previous Hadith “I saw Anas bin Malik offering the funeral prayer for a man, and he stood level with his head. Then another funeral was brought, that of a woman, and they said: ‘O Abu Hamzah! Offer the funeral prayer for her.’ So he stood level with the middle of the bed (the body was upon). ‘Ala’ bin Ziyad said to him: ‘O Abu Hamzah! Is this how you saw the Messenger of Allah (ﷺ) standing in relation to the body of a man and a woman as you have stood?’ He said: ‘Yes.’ Then he turned to us and said: ‘Remember this.’”
