Hadith

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "People do not meet in one of the houses of Allah to recite the Book of Allah and study it together without tranquility descending on them, mercy covering them, the angels encircling them and Allah mentioning them to those who are with Him." [Muslim]
