Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Indeed, the last of the words of prophethood that has been preserved is this: 'If you feel no shame, then do whatever you wish.'"
No one narrated this hadith from Wasil (may Allah have mercy on him) except Layth (may Allah have mercy on him); Mu'tamir (may Allah have mercy on him) is alone in narrating it, and this hadith is not narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) except with this chain.
