Building a mosque for the sake of Allah

عَنْ عُمَرَ بْنِ الْخَطَّابِ، قَالَ سَمِعْتُ رَسُوْلَ اللہِ صَلَّى اللہُ عَلَيْهِ وَسَلَّمَ يَقُوْلُ‏

مَنْ بَنَى مَسْجِدًا يُذْكَرُ فِيْهِ اسْمُ اللہِ بَنَى اللہُ لَهُ بَيْتًا فِی الْجَنَّةِ

Hazrat Umar^ra bin Khattab narrates:

“I heard Allah’s Messenger^sa say, ‘Whoever builds a mosque in which the Name of Allah is mentioned, Allah will build a house for him in Paradise.’”

(Sunan Ibn Majah, Kitab al-Masajid wal Jama’aat, Hadith 735)
