The Messenger of Allah ﷺ said, "Then we came to the seventh heaven. I came upon Ibrahim, and I greeted him. He said, 'Welcome to a son and a prophet.' Then the Bayt al-Mamur was raised up for me, and I asked Jibreel about it. He said, 'This is the Bayt al-Mamur. Seventy thousand angels pray in it every day, and once they leave it, they never return to it again.'"
فذكر حديث الإسراء والمعراج وجاء فيه:
(قال رسول الله ﷺ) فأتينا السماء السابعة… فأتيت على إبراهيم، فسلمت عليه فقال: مرحبا بك من ابن ونبي، فرفع لي البيت المعمور، فسألت جبريل، فقال: هذا البيت المعمور يصلي فيه كل يوم سبعون ألف ملك، إذا خرجوا لم يعودوا إليه آخر ما عليهم.
Bukhari narrated it in "The Beginning of Creation" (3207), and Muslim in "Faith" (164), both through the route of Saeed, who said, Qatada narrated to us, who said, Anas bin Malik narrated to us, from Malik bin Sasaa, and he mentioned it in full.
