Ubaidullah Khawlani says that Hazrat Uthman bin Affan (may Allah be pleased with him) heard the people's discussions regarding the construction of the Prophet's Mosque and said: You people have talked a lot, whereas I heard the Noble Prophet (peace and blessings of Allah be upon him) say that whoever builds a mosque seeking the pleasure of Allah Almighty, Allah Almighty will build for him a similar house in Paradise.
