It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that indeed the Messenger of Allah, peace and blessings be upon him, said: "O people! Abundance of possessions is not wealth; true wealth is the richness of the heart. Then indeed Allah, Blessed and Exalted, will give every servant his complete sustenance that He has written for him, so seek sustenance in a good manner, take what is lawful and leave what is unlawful."
