An important question about Islam! Read it!

[Sunnionline.english]

All friends and forum fellows Assalam u Alaikom W.R.W.B

If some one asks you: give me five best points about Islam which prove that Islam is a complete religion and it is completely according the nature; what you will share with him?
Actually, the same question was asked from me, I have been thinking. Besides, I want to know your points; I hope it will help me to response him better, Insha Allah.

I think it really depends who you are telling these to, for instance the top 5 points to share with a non-muslim would be much different than the top 5 points you would share with a muslim (or even with non-muslims that practice different faiths).
For me though,
1. Belief in Allah alone (not multiple forms, variations, etc. or something you've crafted with your own hands)
2. Prophethood of nabi
3. Scholarship / Preservation (I don't think any other religion compares to Islam in terms of how rigorously it has been preserved)
4. Cleanliness (self explanatory )
5. Rights / Unity / Logic (how everyone's rights have been clearly layed out, so many different people pray in the exact same manner, and alot of the problems in our society have already been accounted for in the shariah )

Thank you, he is a Persian who was born in a Shiite family, but because of the manner of Iranian rulers he became enemy of Islam. He has challenged, you claim Islam is a complete religion so prove it by giving at least five points!
