Ma’an b. ‘Īsā reports that Imām Mālik said, “I am but a man. I make mistakes sometimes and I am correct sometimes, so examine my opinions and accept anything that agrees with the Book and Sunnah; and leave anything that does not agree with the Book and Sunnah.”

Ibn ʿAbd Al-Barr, Jāmi’ Bayān Al-‘Ilm wa Faḍlihi Vol.2 p465.
