Role of the Prophet Muhammad
The Prophet's sole mission was to deliver Quran, the whole Quran, and nothing but Quran (3:20; 5:48-50, 92, 99; 6:19; 13:40; 16:35, 82; 24:54; 29:18; 42:48; 64:12).
Delivering the Quran was such a momentous and noble mission that the Prophet did not have any time to do anything else. Moreover, the Prophet was enjoined in the strongest words from issuing any religious teachings besides the Quran (69:38-47). He was even enjoined from explaining the Quran (75:15-19) — God is the only teacher of the Quran (55:1-2) and the Quran is the best Hadith (39:23 & 45:6).
These Quranic facts are manifested in the historical reality that the words and actions (Hadith & Sunna) attributed to the Prophet did not appear until the second century after his death. The Quran has prophesied the fabrication of Hadith and Sunna by the Prophet's enemies (6:112-115). The Quran teaches us that it was God's will to permit the invention of Hadith and Sunna to serve as criteria for exposing those who believe only with their lips, not in their hearts. Those who are attracted to Hadith and Sunna are proven to be false believers (6:113). Ironically, the books of Hadith report the Prophet's orders to write down nothing from him except the Quran! Shown below are two such Hadiths taken from the Hadithists' most reliable sources, Sahih Muslim and Is-haah Ahmad Ibn Hanbal:
There is no greater blasphemy than distorting the Quran to idolize the prophet Muhammad against his will. Verse 19 of Sura "Muhammad" (47:19) states: "You shall know that there is no god except the one God." Shown below is a photocopy of the regular logo of a Muslim publication THE REVIEW OF RELIGIONS (The London Mosque, 16 Gressenhall Road, London SW18 5QL, England.) Using the Quran's calligraphic style, the publishers of THE REVIEW OF RELIGIONS added the phrase "Muhammad Rasool Allah" in such a way that gives a false impression that such is the Quranic statement of 47:19. What a blasphemy!
The Prophet said, "Do not write down anything from me except the Quran." [Ahmed, Vol. 1, Page 171, and Sahih Muslim]
This Hadith states that the Prophet maintained his anti-Hadith stand until death. [Ahmed, Vol. 1, Page 192]
