Islamic tradition holds that the Quran was revealed to Prophet Muhammad through the angel Gabriel. Muslims regard Muhammad as the final prophet, not merely as a secular “founder” who invented the religion; the revised wording represents the tradition more accurately. Prophet Muhammad fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: Caliph Abu Bakr, Caliph Umar and Imam al-Bukhari are genuine historical terms or names, but each belongs to a different office, patron, text, region or sequence. The compact memory link is therefore Prophet Muhammad together with the factual context above, not the isolated option letter.
