Building mosques for Allah

This hadith speaks about the reward of building mosques for Allah. It is narrated by Mahmud b. Labid and Uthman b. Affan that Uthman wanted to rebuild the mosque of Prophet Muhammad in Medina but people did not like this idea and wanted it to remain as it was before. Then he said that he heard Prophet Muhammad saying that whoever builds a mosque for Allah will be rewarded with a house in paradise like it. This hadith teaches us the importance of building mosques as well as encourages us to do good deeds so we can receive rewards from Allah in return such as being granted a house in paradise when we die or on the Day of Judgment depending on what type of reward it is from Allah's side.
