Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ جَابِرٍ عَنْ عَمَّارٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ بَنَى لِلَّهِ مَسْجِدًا وَلَوْ كَمَفْحَصِ قَطَاةٍ لِبَيْضِهَا بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ.
English Translation
The Prophet (peace be upon him) said: 'Whoever builds a mosque for Allah, even if it is as small as the scratching-place of a sand grouse for its eggs, Allah will build for him a house in Paradise.'
