What is the prescribed Islamic legal punishment for harassing girls, and on what Sharia basis did judges issue divergent rulings in this matter, and are these rulings considered a judgment by other than what Allah has revealed?

Thank you for contacting us. What you mentioned about the judges is not a ruling by other than what Allah has revealed. Rather, it is a discretionary punishment (ta'zir) that is prescribed for every sin for which there is no prescribed legal punishment (hadd) or expiation (kaffarah). Ta'zir can involve flogging, imprisonment, reprimand, and similar measures. It is entrusted to the ruler (wali al-amr) according to what serves the public interest and deters crime, as explained by Ibn al-Qayyim. The evidence may agree that ta'zir is left to the discretion of the ruler according to what serves the public interest and the severity of the crime, which is the view adopted by Shaykh al-Islam Ibn Taymiyyah. Among what is mentioned in this context is the incident of the judge of Medina, Hisham ibn Abdullah al-Makhzumi, who flogged a man 400 lashes and kept him in prison until he died, and his action was not condemned by Imam Malik. We advise you to refer to the Council of Senior Scholars in the Kingdom for further clarification. And Allah knows best.
