Narrated Zirr bin Hubaish: I asked Ubai bin Ka`b, O Abu AlMundhir! Your brother, Ibn Mas`ud said so-and-so (i.e., the two Mu'awwidh-at do not belong to the Qur'an). Ubai said, I asked Allah's Messenger about them, and he said, 'They have been revealed to me, and I have recited them (as a part of the Qur'an), So Ubai added, So we say as Allah's Messenger has said.
