Sahih Muslim 43

Ibn Quhzādh narrated to me, he said, I heard Wahb [bin Zam’ah] saying, on authority of Sufyān [bin Abd il-Mālik], on authority of Ibn al-Mubārak, he said: ‘Baqiyyah [bin al-Walīd] is truthful of tongue however he transmits [Ḥadīth] from those who approach [the Muhaddithīn, i.e. are trustworthy] and from those who turn their backs on [the Muhaddithīn, i.e. and are weak]’.
