I asked Abdullah bin Abu Awfa, "Did the Messenger of Allah ﷺ give Khadijah glad tidings of a house in Paradise?"He replied, "Yes, he gave her glad tidings of a house in Paradise made of hollowed pearls, in which there is no clamor and no fatigue."
قلت لعبد الله بن أبي أوفى: أكان رسول الله ﷺ بشر خديجة ببيت في الجنة؟ قال: نعم، بشرها ببيت في الجنة من قصب، لا صخب فيه ولا نصب.
Bukhari narrated it in the Merits of the Ansar (3819), and Muslim in the Merits of the Companions (2433-72), both through the route of Ismail bin Abu Khalid, who said, I said to Abdullah bin Abu Awfa, and he mentioned it.
