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