WHY ISLAM AND NOT OTHER RELIGIONS ? 
 1-islam gives logical and simple idea for God - he is A perfect God - he is not a man nor a son of man nor an Idol or a trinity nor limited nor created - he is totally unique and to him belongs all the good qualities 
2-Islam accepts all messengers of God -- about 124 0000 and in Islam, we love all the prophet of God and we can’t deny any of them - while in other religions such as Judaism for example - they reject Jesus and Mohammed -- and in Christianity they reject Muhammad ... but in Islam, we accept all . 
3-in Islam, there is no mediator between you and God -- you can pray to God directly - there is no need for someone in between... 
4- Islam is the Only religion that is Not named after a person or a tribe or a group, its name means submission to the One True God, if anyone anywhere at any time lived the life of submission to the true God alone , then he is a Muslim.
 5- In Islam (worship) is not about mere rituals. it's a comprehensive term that includes any deed that pleases God. All good deeds are types of worship, smiling, being sincere at work, saying a nice word, and even treating one's spouse gently, all this is greatly rewarded by God. And in the opposite any deed that doesn't please God is a sin; talking bad about people is a sin, cheating, lying, hurting innocent people, harming the environment. 
6-in Islam God is always forgiving - if you always repent (before death ) he will just accept you no matter how great sins you did >he forgive us out of his own grace - there is no price to be paid in order for him to forgive > so it's not like Christianity which says that God can't forgive except by blood of Jesus .

7-Islam is a way of life – it organises each aspect in your life.. it has solutions and divine guidelines to problems in your life . 
8--the sources of Islam also was collected and saved is also amazing -- it never happen to any book in history --- it's through the uncut chain of known narrators which date to prophet time ... besides the millions who memorised it from cover to cover since that time up till today - besides being documented in front of the prophet by known companions! 
9-Islam prohibits blind following without knowledge and it invite us to use our brains to know truth, it is based on evidence and logic. The rational mind is the basis for religious accountability and responsibility. 
10-the moral system of Islam is v high and perfect and thus the countries that apply Islamic laws in a proper way -- they have less moral crimes.
 11-You won't lose Jesus if you accept Islam, but you will just correct your belief in him , In Islam, Jesus stands a good position in Islam as one of the messengers of God together with other messengers.. they were all special and they were all humans like us-- none of them must be worshiped -- we only worship God who sent them . we believe that Jesus was a noble Messenger of God but not divine,,,, we love Jesus and obey his true teachings and pray like him , fast like him , and a person won't lose Jesus if he accepts Islam -- but you will just correct his belief about him 
12- Paradise in Islam is a real physical life for both Body and soul, you will go there , eating drinking marrying and meeting with prophets and having wonderful eternally unlike in other religions which they think its only spiritual life. 

IN ISLAM THERE IS A PURE & CLEAR CONCEPTS OF GOD 

 God is One and Unique: God has no partners, no equals and no rivals. God has no father, mother, sons, daughters or wives. God alone is worthy of all worship. God is the All-Powerful: God has full authority and power over all things. Obedience to God does not increase His Power, nor does disobedience decrease His power. God is the Most High: There is nothing above or comparable to God. The attributes of God do not resemble that of His creation. No part of God is present in anyone or anything. God is Perfect: God does not have any human limitations, such as resting on the seventh day after He created the universe. God always maintains attributes of perfection and does not do anything to compromise this perfection such as “becoming a man” as claimed by other religions. God does not do ungodly acts, so if God became man and took on human attributes, he would, necessarily, no longer be God. 

REAL HAPPINESS AND INNER PEACE 
Real happiness and peace can be found insubmitting to the commands of the Creator and the Sustainer of this world. God has said in the Quran: Truly, in remembering God do hearts find rest. (Quran, 13:28) On the other hand, the one who turns away from the Quran will have a life of hardship in this world. God has said: But whoever turns away from the Quran,1 he will have a hard life, and We will raise him up blind on the Day of Judgment. (Quran, 20:124) This may explain why some people commit suicide while they enjoy the material comfort money can buy. For example, look at Cat Stevens (now Yusuf Islam), formerly a famous pop singer who used to earn sometimes more than $150,000 a night. After he converted to Islam, he found true happiness and peace, which he had not found in material success
