Narrated Abu Hurairah (RA): Allah’s Apostle (SAW) said, “He who treads the path in search of knowledge, Allah will make that path easy, leading to Paradise for him and those persons who assemble in one of the houses(mosques) of Allah, recite the Book of Allah and learn and teach the Qur’an (among themselves). There will descend upon them tranquility, mercy will cover them, the angels will surround them and Allah will mention them in the presence of those near Him.
(Sahih Muslim: Book 34, #6518).
