"I heard the Messenger of Allah say: 'Whoever builds a mosque for the sake of Allah, Allah will build something similar for him in Paradise.'"  

ابن ماجة:٧٣٦حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا أَبُو بَكْرٍ الْحَنَفِيُّ حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ جَعْفَرٍ عَنْ أَبِيهِ عَنْ مَحْمُودِ بْنِ لَبِيدٍ عَنْ عُثْمَانَ بْنِ عَفَّانَ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ بَنَى لِلَّهِ مَسْجِدًا بَنَى اللَّهُ لَهُ مِثْلَهُ فِي الْجَنَّةِ
