Fadala ibn 'Ubayd reported that the Prophet, may Allah bless him and grant him peace, said, "Do not ask about three:
a man who parts company with the community, rebels the ruler and dies while he is a still a rebel. Do not ask about him. Or a slave or slavegirl who runs away from his master. Or a woman whose husband is absent and who has sufficient provision and then displays her adornments to strangers and mixes freely. Do not ask about three: a man who contends with Allah regarding His cloak. His cloak is pride and His wrapper is His might. Also a man who doubts the command of Allah. and someone who despairs of Allah's mercy."
