Allaah says (interpretation of the meaning): “The mosques of Allaah shall be maintained only by those who believe in Allaah and the Last Day; perform As-Salaah (Iqaamat-as-Salaah), and give Zakaah and fear none but Allaah. It is they who are on true guidance” [al-Tawbah 9:18]

Ibn Majaah narrated from Jaabir ibn ‘Abd-Allaah that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever builds a mosque for the sake of Allaah, like a sparrow’s nest or even smaller, Allaah will build for him a house in Paradise.”
