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: "Abundance of possessions is not wealth, rather (true) wealth is the richness of the heart (contentment)." Muslim has also narrated it with his chain from Sayyiduna Abu Hurairah (may Allah be pleased with him) as a marfu' (attributed to the Prophet) narration.
