sheik-ibrahim-nyass-noujoum --> The ninth argument

Now, ask the same person the give that un-welcomed news to someone in a remote countryside. It would be very hard for him to do so. As for Muhammad (pbuh), he was charged with walking day and night during all of his life to free people that he knew not, or rather knew only because of their hate, and their harm and scorn. And in spite of all that, he did not seek relief from his duty. On the contrary, he hurried in front of them so as to fulfil to the letter his duty, the matter that brought him to endure much sufferance while spreading the divine religion.
Allah said: "The first Companions of the Prophet have more merit than those who supported the religion later." If this is said of the Companions, all the more reason, that the greatest merit should fall to the Prophet who suffered much more than the others.

The ninth argument is owed to the fact that the religion of Islam is the best of religions. It is then only logical that Muhammad would be the best Prophet.
By the Will of Allah, the religion of Islam has abolished the rest of religions, thus, is not it the best, especially because the Prophet (pbuh) has said: "He who established a good custom shall have rewards as many as the number of times this custom would have been practiced by others until the Day of the Resurrection." The religion of Islam has more rewards and credits than the other religions, by means of consequence; its establisher must be more deserving than other prophets.
