Thus, be content with him as a leader and as a guide to salvation. Indeed, I have not fallen short in advice to you, and, however much you may strive, you will never attain that degree of concern for your welfare that I have for you”. Commentary In this part of the letter, Imam ‘Ali (as) emphasizes two points: 1. Muhammad's Religion Is The Best In The World As we know that the prophets have been sent to people at different times and under different conditions.
The more backward the people, the simpler was the prophets' training and educating people. Their schedules were like those of present-day schools where in elementary schools simpler books and methods are used whereas in the high schools we have more complicated programs.
Since the more ancient Prophets were sent to people who had not progressed enough, their methods of educating people were more elementary, but since the Prophet of Islam was the last of the Prophets,[^1] and his religion is eternally the way of life for all men,[^2] there it is better to be said that "nobody has told us of Allah like the Prophet (S) has", and his religion is the most comprehensive of all religions.[^3] Anybody adopting another way of life is rejected.[^4] It is also right to say: Only he is to be chosen as the leader[^5] since his religion is the most comprehensive, his leadership the most perfect and his commandments the most beneficial.
