Murrah (may Allah have mercy on him) said that Abdullah (may Allah be pleased with him) said, concerning the words of Allah Almighty: "And gives wealth, despite his love for it, to relatives, orphans and the needy" [Surah al-Baqarah: 177]: Give charity while you are healthy and covet wealth, hoping to become rich and fearing poverty.
