The Messenger of Allah ﷺ said in the long narration of the Night Journey, "Then I was taken up to the seventh heaven. Jibreel asked for it to be opened, and it was said, 'Who is this?'He replied, 'Jibreel.'It was said, 'And who is with you?'He answered, 'Muhammad.'It was said, 'Has he been sent for?'He replied, 'He has been sent for.'So it was opened for us, and there I saw Ibrahim with his back resting against the Frequented House, which seventy thousand angels enter every day, never to return to it again..." and the rest of the hadith.
أن رسول الله ﷺ قال في حديث الإسراء الطويل: ثم عرج بي إلى السماء السابعة، فاستفتح جبريل، فقيل: من هذا؟ قال: جبريل. قيل: ومن معك؟ قال: محمد. قيل: وقد بعث إليه؟ قال: قد بعث إليه. ففتح لنا، فإذا أنا بإبراهيم مسندا ظهره إلى البيت المعمور، وإذا هو يدخله كل يوم سبعون ألف ملك، لا يعودون إليه… الحديث.
Muslim narrated it in the Book of Faith (162) from Shayban bin Farroukh, who said, "Hammad bin Salama narrated to us, who said, Thabit Bunani narrated to us, from Anas bin Malik," and he mentioned it.
