‘Abd ar-Rahman b. Abza told that God's messenger used to say in the morning, “We have reached the morning following the original religion of Islam, the assertion of God’s unity, the religion of our Prophet Muhammad, and the rite of our father Abraham who was a hanif and was not one of the polytheists." [cf. Qur’an, ii. 135; iii, 95; vi, 161; xvi, 123.]
Ahmad and Darimi transmitted it.
