Mahmood bin Labeed says that when Sayyiduna Uthman (may Allah be pleased with him) intended to expand the Prophet’s Mosque, instead of expressing happiness, the people preferred to keep it in its original form. But Sayyiduna Uthman (may Allah be pleased with him) said: I heard the Prophet (peace and blessings of Allah be upon him) say that whoever participates in the construction of a mosque for the sake of Allah’s pleasure, Allah builds for him a similar house in Paradise.
