Question: “May Allaah be good to you. Is lying permissible for the purpose of calling to Allaah?”
No, calling to Allaah is based upon truthfulness. There is no good in lying. Except for in the instance of rectification, rectification between the people. Rectification between the people, there is no problem with lying for the purpose of rectification, (which is) an overriding benefit. Likewise (lying) between the spouses for the sake of maintaining the close relationship between the two. So one of them lies to the other in order to rectify their relationship. There is no problem with this.
