It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him and his family) said: There are four virtues; if you possess them, you should not grieve over anything lost from the world: safeguarding trust, speaking the truth, good character, and chastity in food (i.e., earning lawful sustenance sufficient for your needs).
