I don't outbid on Islam. Islam a brilliant religion by itself and doesn't need any preaching or missionary work or me.
We cay say there are so many sects, cults, religions, philosophies, and movements in the world, all of which claim to be the right way or the only true path to God. How can one determine which one is correct or if, in fact, all are correct? The method by which the answer can be found is to clear away the superficial differences in the teachings of the various claimants to the ultimate truth, and identify the central object of worship to which they call, directly or indirectly. Can we either claim that all men are Gods or that specific men were God or that nature is God or that God is a figment of man's imagination.
It may be argued that all religions teach good things so why should it matter which one we follow. I made some searching and I couldn’t find a sharp answer but I found something interesting stated in the Koran:
Creation-worship is the greatest sin that man can commit because it contradicts the very purpose of his creation. Man was created to worship Allah alone, consequently, the worship of creation, which is the essence of idolatry, is the only unforgivable sin. One who dies in this state of idolatry has sealed his fate in the next life. This is not an opinion, but a revealed fact stated by Allah in his final revelation to man:
"Verily Allah will not forgive the joining of partners with Him, but He may forgive (sins) less than that for whom so ever He wishes"(Soorah An- Nisaa 4:48 and 116)
Buddha was a reformer who introduced a number of humanistic principles to the religion of India. He did not claim to be God nor did he suggest to his followers that he be an object of worship. Yet, today most Buddhists who are to be found outside of India have taken him to be God and prostrate to idols made in their perception of his likeness.
This is also what I found regarding Racism in Quran:
The noblest of you in the sight of Allah*, is the most pious (righteous) of you” (Qur'an 49:13).
As a result of following these teachings, many people have banished racism from their thoughts and actions. You can still see racial harmony today in the mosques of cosmopolitan cities. You will find people of various colors worshipping together, all with equal status before God. Rich or poor, black or white, kind or pauper all line up side by side to worship. No special preference is given to anyone based on color or social status. The leader in a mosque is appointed for his learning in the religious sciences, regardless of skin color. There is no such concept as a 'black mosque' or 'white mosque'. Islam removes such destructive concepts.
Regarding woman, most Islamic societies aren't theocratic. I find it interesting that the three largest Islamic countries have had women heads of state (Indonesia, Pakistan, Bangladesh), while the same can't be said of the three largest Christian countries.
