[Machine] The Messenger of Allah ﷺ said: "Whoever builds a mosque for Allah, even if it is as small as a bird's nest, Allah will build for him a house in Paradise." Al-Abbas said: Ahmad bin Yunus said that it was said to Abu Bakr bin Ayyash: "People differ with you regarding this hadith, they do not consider it authentic." Abu Bakr bin Ayyash replied: "We heard this from Al-Amash, and Al-Amash was a young man."  

قَالَ رَسُولُ اللهِ ﷺ مَنْ بَنَى لِلَّهِ مَسْجِدًا وَلَوْ مِثْلَ مَفْحَصِ قَطَاةٍ بَنَى اللهُ لَهُ بَيْتًا فِي الْجَنَّةِ قَالَ الْعَبَّاسُ قَالَ أَحْمَدُ بْنُ يُونُسَ قِيلَ لِأَبِي بَكْرِ بْنِ عَيَّاشٍ إِنَّ النَّاسَ يُخَالِفُونَكَ فِي هَذَا الْحَدِيثِ لَا يَرْفَعُونَهُ فَقَالَ أَبُو بَكْرِ بْنُ عَيَّاشٍ سَمِعْنَا هَذَا مِنَ الْأَعْمَشِ وَالْأَعْمَشُ شَابٌّ
