The Prophet ﷺ said, "No people gather in one of the houses of Allah the Exalted, reciting the Book of Allah and studying it together, except that tranquility descends upon them, mercy envelops them, the angels surround them, and Allah mentions them among those in His presence."
حدثنا عثمان بن أبي شيبة حدثنا أبو معاوية عن الأعمش عن أبي صالح
عن النبي ﷺ قال ما اجتمع قوم في بيت من بيوت الله تعالى يتلون كتاب الله ويتدارسونه بينهم إلا نزلت عليهم السكينة وغشيتهم الرحمة وحفتهم الملائكة وذكرهم الله فيمن عنده
