حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ، عَنْ سَعْدِ بْنِ عُبَيْدَةَ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ عُثْمَانَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ خَيْرُكُمْ مَنْ تَعَلَّمَ الْقُرْآنَ وَعَلَّمَهُ ‏"‏ ‏.‏

Abu Hurairah reported the Prophet (ﷺ) as saying

No people get together in a house of the houses of Allah (i.e. a mosque), reciting the Book of Allah, and learning it together among themselves, but calmness (sakinah) comes down to them, (Divine) mercy covers them (from above), and the angels surround them, and Allah makes a mention of them among those who are with Him.
