Mishkat al-Masabih

Abu Burda* told that when the Prophet (ﷺ) sent his grandfather Abu Musa and Mu'adh to the Yemen he said, “Make things easy and do not make them difficult; gladden and do not scare; comply with one another and do not disagree.” (Bukhari and Muslim.) * This should be Sa'id b. Abu Burda on his father’s authority. C f. Bukhari, Maghazi, 60.
