It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she said: I heard the Messenger of Allah (peace and blessings be upon him) say: "There is no person who brings barren land to life, and then a thirsty living creature drinks from it or a seeker of sustenance (bird or animal) obtains something from it, except that Allah writes a reward for him because of it."
