وَعَنْ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عَلَيْهِ وَسَلَّمَ: «مَنْ بَنَى لِلَّهِ مَسْجِدًا بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ»
‘Uthman reported God's Messenger as saying, “If anyone builds a mosque for God, God will build a house for him in paradise.” (Bukhari and Muslim.)
