It is narrated from Sayyiduna Shaddad bin Aws (may Allah be pleased with him); he said: The Messenger of Allah (peace and blessings be upon him) said to me: "O Shaddad bin Aws, when you see the people hoarding gold and silver, then you hoard these words: 'Allahumma inni as'aluka al-thabata fi al-amr, wa al-azimata ala al-rushd, wa as'aluka mujibati rahmatik, wa aza'ima maghfiratik, wa as'aluka shukra ni'matik, wa husna ibadatik, wa as'aluka qalban saliman, wa lisanan sadiqan, wa as'aluka min khayri ma ta'lam, wa a'udhu bika min sharri ma ta'lam, wa astaghfiruka lima ta'lam, innaka anta allam al-ghuyub' (O Allah, I ask You for steadfastness in the matter (of religion) and firm resolve upon right guidance; I ask You for the things that make Your mercy certain and the things that ensure Your forgiveness; I ask You for gratitude for Your blessings and excellence in worshipping You; I ask You for a sound heart and a truthful tongue; I ask You for the good of what You know, I seek refuge in You from the evil of what You know, and I ask Your forgiveness for what You know. Indeed, You are the Knower of the unseen)."
