Masrūq – Allah have mercy on him – said:

Sufficient as knowledge for a person is that he fears Allah, and sufficient as ignorance for a person is that he feels impressed with the knowledge he has.

Al-Ājurrī in Akhlāq Al-‘Ulamā’ no.40.

Masrūq was one of the major Tābi’īn, or students of the Companions. He accompanied Ibn Mas’ūd and was one of his students who became senior teachers and muftis after him. He reported from numerous other Sahābah. It is said that he was called Masrūq (literally: stolen) because he was kidnapped as a child but later recovered. He died in 62H or 63H.
