It has also been narrated by Sa' d b. Abu Burda through his father through his grandfather that the Prophet of Allah (ﷺ) sent him and Mu' adh (on a mission) to the Yemen, and said (by way of advising them): Show leniency (to the people) ; don' t be hard upon them; give them glad tidings (of Divine favours in this world and the Hereafter) ; and do not create aversion. Work in collaboration and don' t be divided.
