I heard ʿUthman bin ʿAffan saying, when people argued too much about his intention to reconstruct the mosque of Messenger of Allah ﷺ, "You have talked too much. I heard the Prophet ﷺ saying, 'Whoever built a mosque, (Bukair thought that ʿAsim, another sub-narrator, added, "Intending Allah's Pleasure"), Allah would build for him a similar place in Paradise.' "  

أَنَّهُ سَمِعَ عُثْمَانَ بْنَ عَفَّانَ يَقُولُ عِنْدَ قَوْلِ النَّاسِ فِيهِ حِينَ بَنَى مَسْجِدَ الرَّسُولِ ﷺ إِنَّكُمْ أَكْثَرْتُمْ وَإِنِّي سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ مَنْ بَنَى مَسْجِدًا قَالَ بُكَيْرٌ حَسِبْتُ أَنَّهُ قَالَ يَبْتَغِي بِهِ وَجْهَ اللَّهِ بَنَى اللَّهُ لَهُ مِثْلَهُ فِي الْجَنَّةِ
