Salamah bin Kuhayl relates that it is narrated from Sayyiduna Jundub bin Sufyan (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No servant conceals a secret but that Allah clothes him in its cloak: if it is good, then good, and if it is evil, then evil."
