Currently, many teenagers rarely follow the rules of the Quran and Hadith. They often neglect gadgets and play games. Many teenagers have also started dating, forgetting the sin of excessive dating. Their behavior and actions often go beyond Islamic law and the laws in Indonesia, particularly in Aceh. Many teenagers engage in premarital sex, premarital pregnancy, drug use, brawls, and even murder of their teachers or those around them. Adolescence is a time of intense attention seeking, especially from those closest to you. This attention requires guidance and direction from the right people to prevent undesirable outcomes.
