Is it not rational to test your faith? There are thousands of religions in the world.The major religions which have a large number of followers are Judaism, Christianity, Confucianism, Zoroastrianism, Hinduism, Buddhism,Jainism, Taoism, Shintoism, and Sikhism.

How can we identify the true religion when the adherents of all religions claim that their ’s isthe true one?

This is not difficult. One can search the true religion from the bulk of religions if he is sincerein his research and investigation.

For instance, If you study all the major religions of the world, the outcome of yourunprejudiced research would be as follows:

• Islam is the only religion which agrees with the human nature.
  
  
  
  Allah’s handiwork according to the pattern on which He has made mankind: (30:30).
  
  For example, The engineers always try to foresee student’s concerns in such areas as safety and the environment when they plan to design school buildings. Similarly the laws of Islam are made by Allah Subhanahu taala according to the pattern on which He has created the human beings and the environment in which they were planed to live.

• Islam is the only religion which never collides with any of the cosmic laws.
  
  He Who created the seven heavens one above another: Do you see any fault in the work of Merciful? Turn up your eyes: Can you detect any rift? Then look once more and yet again: your eyes will in the end grow dim and weary. (67:3-4)
  
  The perfect order and harmony in the vast space, visible and invisible to us, following precise laws of motion, proves absolute unity and supreme authority of a single creator.
  
  The multiple laws of nature are closely connected with each other in the continuous working of the universe. There is no gap, no overlapping nor discontinuity. This phenomenon is one of the signs of the unity of the creator. Thus, the laws of religion and laws of cosmos have the same origin and therefore the question of collision does not arise.

• Islam is the only religion which gives strong emphasis on pondering, reasoning and rational thinking. Islam demands its followers to understand the Holy Quran and then show its applications in practical life. Quran has repeatedly advised the Muslims to ponder, to reflect and to understand its message. Quran has made it very clear that it is addressing to only those people who are intellectuals.
  
  
  
  “Thus do We explain the signs in detail for those who understand (7:32)
  
  Thus do We detail our message for people who have knowledge (7:32)
  
  Here are signs for people who are wise ( 30:28)
  
  Verily there are signs for people who reflect (39:42)
  
  Verily in this are signs for people endued with intelligence. (13:3)
  
  Quran was revealed in Arabic which was the language of Arabs.
  
  
  
  We have revealed (Quran) in Arabic so that you may understand (12:2)
  
  Soon after the introduction of Islam in non-Arab countries, the people of that countries translated it into their own language. Many people learned Arabic just to understand Quran.
  
  Christians and Jews who live in English speaking countries also needed a translation of the Bible. But the first English translation of the Bible appeared in the 1380’s. Mar tin Luther translated Bible into German language in 1534.
  
  Why the Bible was translated so late into the language of the people? Because the evangelists never allowed to arrange translations and discouraged people to read it in their own language.
  
  Similarly in Hindus, a special group of people known as Brahmans were allowed to read the religious books.
