Ubaidullah al-Khaulini reported: 'Uthman bin 'Affan listened to the opinion of the people (which was not favourable) when he rebuilt the mosque of the Messenger of Allah (ﷺ) . Thereupon he said: You have not been fair to me for I have heard from the Messenger of Allah (ﷺ) saying: He who built a mosque for Allah, the Exalted, Allah would build for him a house in Paradise. Bukair said: I think he (the Holy Prophet) said: While he seeks the pleasure of Allah (by building the mosque). And in the narration of Ibn 'Isa (the words are):" (a house) like that (mosque) in Paradise."

Abu Talha, the Companion of Allah's Messenger (ﷺ) , reported Allah's Messenger (ﷺ) having said: Verily, angels do not enter the house in which there is a picture. Busr reported: Zaid fell ill and we went to inquire after his health and (found) that there was hanging at his door a curtain with a picture on it. I said to 'Ubaidullah Khaulani who had been under the patronage of Maimuna, the wife of Allah's Apostle (ﷺ) : Did not Zaid himself inform us before about (the Holy Prophet's command pertaining to the pictures), whereupon 'Ubaidullah said: Did you not hear when he said:" Except the prints on the cloth"?

'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."
