Each prophet had a mission to prepare the world for the teaching of the next; each one prophesied the coming of the next, and the work was thus continued by all the prophets until Mohammed, the Khatim al Mursalin, the last messenger of divine wisdom and the seal of the prophets, came on his mission, and in his turn gave the final statement of divine wisdom: "None exists but Allah." This message fulfilled the aim of prophetic mission. This final definition is a clear interpretation of all religions and philosophies in the most apparent form. There was no necessity left for any more prophets after this divine message, which created the spirit of democracy in religion by recognizing God in every being. By this message man received the knowledge that he may attain the highest perfection under the guidance of a perfect murshid or spiritual teacher.
