The Prophet ﷺ said: “Whoever builds a masjid for Allah, Allah builds for him the like of it in Paradise.” (al-Bukhārī & Muslim). And: “Whoever builds for Allah a masjid, even the size of a sandgrouse's nest, Allah builds for him a house in Paradise.” (Ibn Mājah) — so any share counts.
العربية: عن عثمان بن عفان رضي الله عنه أنّ النبيّ ﷺ قال: «مَن بنى مسجدًا لله بنى الله له في الجنة مثله». (البخاري ومسلم).
Contribute to building or maintaining a masjid — however small the amount — and earn a home in Paradise.
