1.He was the last Prophet of Allah;
2.Allah revived through him the same genuine faith which had been conveyed by all the Prophets;
3.This original message was corrupted, and split into various religions by peoples in different ages, who indulged in interpolations and admixture. These alien elements were eliminated by Allah and Islam, in its pure and original form, was transmitted to mankind through Mohammad (PBUH);
4.Since there was to be no messenger after Mohammad (PBUH), the Book revealed to him was preserved word for word so that it should be a source of guidance for all times;
5.The life of Mohammad (PBUH), and the manner in which he conducted himself, was also recorded in a unique manner by his companions and by later compilers of the Tradition. A more complete and authentic account of the life , sayings and actions of any Prophet or historical personage, has never been compiled;
6.In this way, the Quran and the authentic Sunnah of the Prophet together became a reliable source of knowing Islam.
