It is narrated from Sayyiduna Abu al-Darda' (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Free yourselves from the worries and anxieties of this world as much as you can, for whoever has this world as his greatest concern, Allah puts lack of blessing and disorder into his livelihood and places his poverty before his eyes; and whoever has the Hereafter as his greatest concern, Allah brings his affairs together for him and places his richness in his heart. And no servant turns to Allah with his whole heart except that Allah makes the hearts of the believers incline towards him with love and mercy, and Allah is quicker towards him with every good."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Abu al-Darda' (may Allah be pleased with him) except with this chain; Muhammad bin Bishr is alone in narrating it."
