Sayyidah Aishah (may Allah be pleased with her) narrates that the Prophet (peace and blessings be upon him) said: "Whoever builds a mosque for Allah Almighty, not intending by it showing off or seeking fame, Allah Almighty will build for him a house in Paradise."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, al-Muthanna bin al-Sabbah, whom Yahya al-Qattan and a group declared da'if (weak); according to one report Yahya bin Ma'in declared him thiqah (trustworthy), and according to another report he too declared him da'if.
