مسند أحمد

It was narrated from `Uthman bin `Affan (رضي الله عنه) that the Prophet (ﷺ) said: `The best of you is the one who teaches Qur`an or learns it.” Muhammad bin Ja`far and Hajjaj said: Abu `AbdurRahman said: That is what made me sit in this place (i.e., become a teacher). Hajjaj said: Shu`bah said: Abu `Abdur-Rahman did not hear (it) from `Uthman (رضي الله عنه) or from ‘Abdullah, but he heard it from ‘Ali (رضي الله عنه). My father said and Bahz said: (It was narrated from) Shu`bah who said: `AIqamah bin Marthad told me. “The best of you is the one who learns Qur`an and teaches it.`

`Affan told us: Shu`bah told us: `Alqamah bin Marthad told me... and he said in it: “Whoever learns the Qur`an or teaches it.”
