It is narrated from Safwan bin Sulaim that a man said to the Messenger of Allah, peace be upon him: "May I lie to my wife?" The Messenger of Allah, peace be upon him, said: "Lying is not good and there is no goodness in it." Then the man said: "May I make a promise to my wife and say to her, 'I will do this for you, I will make this for you'?" The Messenger of Allah, peace be upon him, said: "There is no sin in that."
