Islam The Way of Life

Every Muslim must believe in what the Prophet (Peace & Blessings of Allaah be upon Him) has told us, and not doubt a single word of it, because what the Prophet says is wahy (revelation) revealed to him by Allaah: Whoever doubts what the Prophet (Peace & Blessings of Allaah be upon Him) said or doubts that it is wahy is a kaafir who has left Islam
