'Abdullah al-Khaulani reported that when 'Uthman bin 'Affan tried to rebuild the mosque of Allah's Messenger (ﷺ) the people began to talk about this. 'Uthman bin 'Affan said: You discuss it very much whereas I have heard Allah's Messenger (ﷺ) as saying: "He who builds a mosque .." and the narrator Bukair said: I think he also said: (for) seeking the pleasure of Allah, Allah would build (a similar house for him in Paradise), and in the narration of Harun (the words are): "A house for him in Paradise."
