It is narrated from Sayyiduna Sufyan bin Abdullah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The one who shows contentment and satiation with what he has not been given is like one who wears two garments of falsehood."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sufyan bin Abdullah (may Allah be pleased with him) only with this chain."
