Verse 17

يَـٰبُنَىَّ أَقِمِ ٱلصَّلَوٰةَ وَأْمُرْ بِٱلْمَعْرُوفِ وَٱنْهَ عَنِ ٱلْمُنكَرِ وَٱصْبِرْ عَلَىٰ مَآ أَصَابَكَ إِنَّ ذَٰلِكَ مِنْ عَزْمِ ٱلْأُمُورِ

O my son, observe the contact prayer; enjoin righteousness and forbid evil and be patient in the face of adversity. Indeed this reflects strength of character.
