Brief Explanation
Benefit: It is narrated from Sayyiduna Jabir radi Allahu anhu that the Prophet sallallahu alayhi wa sallam said: "Whoever digs a well of water from which living beings—jinn and humans, birds and beasts—drink, Allah Ta'ala will reward him with recompense on the Day of Resurrection. And whoever builds a mosque the size of a bird's nest or even smaller, Allah Ta'ala will build a house for him in Paradise." [التاريخ الكبير للبخاري : 1/332 ، وسنده صحيح]
