حديث أبى هريرة عن النبي صلى الله عليه وسلم قال (ما اجتمع قوم في بيت من بيوت الله يتلون كتاب الله ويتدارسونه فيما بينهم إلا نزلت عليهم السكينة وغشيتهم الرحمة وحفتهم الملائكة وذكرهم الله فيمن عنده). (صحيح مسلم)
Abu Hurairah, may God be pleased with him said, that the Prophet, peace be upon him, said: No people gather in a mosque, reciting the Quran, and studying it amongst themselves but tranquillity descends upon them and they are overwhelmed with mercy while the Angels surround them and God mentions them with those who are with Him.
