Bishr bin Hayan says that once Sayyiduna Wathilah bin Asqa’ came to us while we were constructing our mosque. He came to us, greeted us with salam, and said: I heard the Prophet (peace and blessings be upon him) say: Whoever builds a mosque in which prayers are offered, Allah will build for him a house better than it in Paradise.
