یٰبُنَیَّ اَقِمِ الصَّلٰوةَ وَاْمُرْ بِالْمَعْرُوْفِ وَانْهَ عَنِ الْمُنْكَرِ وَاصْبِرْ عَلٰی مَاۤ اَصَابَكَ اِنَّ ذٰلِكَ مِنْ عَزْمِ الْاُمُوْرِ ۟

“"O my son! establish regular prayer, enjoin what is just, and forbid what is wrong: and bear with patient constancy whatever betide thee; for this is firmness (of purpose) in (the conduct of) affairs.”
