How sound is the statement that the Prophet's — may Allah bless him and grant him peace — assistance to his wives in household chores is invalid, based on the premise that his actions were limited to masculine tasks or what exclusively concerned him, and that what was reported by Qadi Iyad in "Ash-Shifa" regarding his sweeping the house and kneading dough is weak?

The Prophet, peace and blessings be upon him, used to serve himself and his family out of humility and to teach his community. He would attend to the needs of his family and dependents in his home, and when the time for prayer came, he would go out for it. This indicates serving the household and its people, humility, and abandoning arrogance. Some scholars believe that this service does not include matters exclusive to his wives, due to the unlikelihood of their approval of such.
