The Messenger of Allah ﷺ said, "In the last days, there will emerge a people young in age and foolish in mind. They will recite the Quran, but it will not pass beyond their throats. They will speak words from the best of creation, yet they will pass through the religion as an arrow passes through its target."

قال رسول الله ﷺ يخرج في آخر الزمان قوم أحداث الأسنان سفهاء الأحلام يقرءون القرآن لا يجاوز تراقيهم يقولون من قول خير البرية يمرقون من الدين كما يمرق السهم من الرمية
