I heard Messenger of Allah ﷺ as saying: He who builds a mosque for Allah, Allah would build for him (a house) in Paradise like it.
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ بَنَى مَسْجِدًا لِلَّهِ بَنَى اللَّهُ لَهُ فِي الْجَنَّةِ مِثْلَهُ
"Whoever builds a Masjid in which Allah is remembered, Allah, (the Mighty and Sublime) will build for him a house in Paradise."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ بَنَى مَسْجِدًا يُذْكَرُ اللَّهُ فِيهِ بَنَى اللَّهُ ﷻ لَهُ بَيْتًا فِي الْجَنَّةِ
"I heard the Messenger of Allah say: 'Whoever builds a mosque in which the Name of Allah is mentioned, Allah will build a house for him in Paradise.'"
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ بَنَى مَسْجِدًا يُذْكَرُ فِيهِ اسْمُ اللَّهِ بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ
"The Messenger of Allah said: 'Whoever builds a mosque for the sake of Allah (from his own wealth), Allah will build a house for him in Paradise.'"
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ بَنَى لِلَّهِ مَسْجِدًا مِنْ مَالِهِ بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ
I heard the Messenger of Allah( ﷺ) say: ʿWhoever builds a mosque for the sake of Allah, Allah will build for him a house like it in Paradise.ʿ
أَنْ يَبْنِيَ مَسْجِدَ الْمَدِينَةِ فَكَرِهَ النَّاسُ ذَاكَ وَأَحَبُّوا أَنْ يَدَعُوهُ عَلَى هَيْئَتِهِ فَقَالَ عُثْمَانُ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ بَنَى مَسْجِدًا لِلَّهِ بَنَى اللهُ لَهُ بَيْتًا فِي الْجَنَّةِ مِثْلَهُ
