Hazrat Luqman was a wise person and a great man, he was always fighting with his selfishness and always was working on purification of the soul, and God sent his blessings on him. Hazrat Luqman says to his son:
“يَا بُنَيَّ أَقِمِ الصَّلَاةَ وَأْمُرْ بِالْمَعْرُوفِ وَانْهَ عَنِ الْمُنكَرِ وَاصْبِرْ عَلَىٰ مَا أَصَابَكَ إِنَّ ذَٰلِكَ مِنْ عَزْمِ الْأُمُورِ ﴿١٧﴾”
O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination. (17)[1]
