Gentlemen! In my previous six lectures I have trIed to prove in the light of sound, and authentic arguments that of all the great men who have served humanity, only the Prophets of Allah are the ones whose noble examples ought to be followed And the most perfect and complete life available to us today is that of Prophet Muhammad (Peace be upon him) which makes him the best and eternal role model for all mankind. Once we have shown that Prophet Muhammad (PBUH) is the eternal and perfect model the question arises— what are his universal teachings that lead to eternal success? What message has he brought to the world and what are the essential features of that message for which the last of God’s Messengers was sent to this world? How did this Message modify & and complete the messages sent down through the earlier Prophets?
