Do not mix truth with falsehood, or hide the truth when you know it. Keep up the prayer, pay the prescribed alms, and bow your heads [in worship] with those who bow theirs. How can you tell people to do what is right and forget to do it yourselves, even though you recite the Scripture? Have you no sense? Seek help with steadfastness and prayer--though this is hard indeed for anyone but the humble, who know that they will meet their Lord and that it is to Him they will return.
