Abdullah al-Khaulani reported that when Uthman b. 'Affan tried to rebuild the mosque of Allah's Messenger (ﷺ) the people began to talk about this. Uthman b. '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."
حَدَّثَنِي هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، وَأَحْمَدُ بْنُ عِيسَى، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، - وَهُوَ ابْنُ الْحَارِثِ - أَنَّ بُكَيْرًا، حَدَّثَهُ أَنَّ عَاصِمَ بْنَ عُمَرَ بْنِ قَتَادَةَ حَدَّثَهُ أَنَّهُ، سَمِعَ عُبَيْدَ اللَّهِ الْخَوْلاَنِيَّ، يَذْكُرُ أَنَّهُ سَمِعَ عُثْمَانَ بْنَ عَفَّانَ، عِنْدَ قَوْلِ النَّاسِ فِيهِ حِينَ بَنَى مَسْجِدَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِنَّكُمْ قَدْ أَكْثَرْتُمْ وَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ بَنَى مَسْجِدًا - قَالَ بُكَيْرٌ حَسِبْتُ أَنَّهُ قَالَ - يَبْتَغِي بِهِ وَجْهَ اللَّهِ بَنَى اللَّهُ لَهُ مِثْلَهُ فِي الْجَنَّةِ " . وَفِي رِوَايَةِ هَارُونَ " بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ " .
