This Hadith sheds light on seven points. First, we are informed of certain young men who had left their homes and come to the Prophet (PBUH) in order to receive religious training from him. This shows that a student of knowledge should not hesitate to set forth on a journey in the pursuit of knowledge. Second, a teacher/mentor is supposed to have firsthand information about the affairs and requirements of students and to take measures accordingly. Third, after graduation or the completion of an orientation course in religious studies, the beneficiaries are also required to impart religious knowledge and training to those who lack it. Fourth, they should also tell people to do what is commanded by the Shari`ah (Islamic Law) and to shun what it prohibits. Fifth, an arrangement must be made for a Mu'adhdhin to call people to Salat (prayers). Sixth, in case each one of the congregation is equally qualified to lead the Salat, the one who is most senior in age should perform the duty. The first prerequisite of becoming an Imam is the ability to recite Qur'an well and in the right manner. The second in priority is that person who is well-grounded in the religion - Qur'an and Hadith. In other words, a good Qari (reciter) is most fit to become an Imam and the second choice should be the one who has the mastery of religious knowledge. Seventh, the crux of the matter is that on all occasions and at all places, believers are under obligation to take care to establish congregational prayer after the prayer-call.
