Hadith 533
Mahmud bin Labid reported: When 'Uthman bin 'Affan intended to build the mosque (of the Prophet) the people did not approve of it. They liked that it should be kept in the same state. Thereupon he said: I heard the Messenger of Allah (ﷺ) say: He who built a mosque for Allah, Allah would build a house for him like it in Paradise.
Hadith 533
Mahmud bin Labid reported that 'Uthman bin 'Affan decided to rebuild the mosque (of Allah's Apostle (ﷺ) in Madinah) but the people did not like this idea and they wished that it should be preserved in the same (old) form. Thereupon he (Hadrat 'Uthman) said: I heard Allah's Messenger (ﷺ) as saying: He who builds a mosque for Allah, Allah would build for him (a house) in Paradise like it.
