"The Messenger of Allah ﷺsaid: 'If there are three people, let one of them lead the others in prayer, and the one who has the most right to lead the prayer is the one who recites (knows) the most (Qur'an)."'  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا كَانُوا ثَلاَثَةً فَلْيَؤُمَّهُمْ أَحَدُهُمْ وَأَحَقُّهُمْ بِالإِمَامَةِ أَقْرَؤُهُمْ
