[Machine] The Messenger of Allah ﷺ said, "Perhaps you will recite while the imam is reciting." He repeated this three times. They said, "Indeed, we do that." He said, "Do not do so, except that one of you recites with the opening chapter of the Book."  

قَالَ رَسُولُ اللهِ ﷺ لَعَلَّكُمْ تَقْرَءُونَ وَالْإِمَامُ يَقْرَأُ قَالَهَا ثَلَاثًا قَالُوا إِنَّا لَنَفْعَلُ ذَاكَ قَالَ فَلَا تَفْعَلُوا إِلَّا أَنْ يَقْرَأَ أَحَدُكُمْ بِفَاتِحَةِ الْكِتَابِ
