Saudi Arabia is the most important Muslim country that is specifically known for its religious monuments including mosques and mainly the origin of the most important religion ‘Islam’. In the Kingdom of Saudi Arabia citizens take their religion VERY seriously and by ‘seriously’ I mean very SERIOUSLY! In Saudi Arabia, if one Muslim has abandoned Islam the price for it is death sentence/killed. I may have scared most of you right in the beginning of this read but my main agenda was to enlighten you all with the truth. On many occasions and on many forums, I have to think and observe a question repeatedly that asks whether Saudi Arabia allows other religions to be followed or practiced within it. Before I could start thinking about the possibilities I had to do a lot of digging and ask many of my family friends and relatives who have visited or are residing in Saudi Arabia.[irp]
The same answer came repeatedly and that was not a simple “Yes” or ‘NO’. They did not wish to give me reasons or share their own point of views or anything further. With this, I had to do a lot of research of my own. After which I finally had enough matter to put forward for you all. Saudi Arabia does not allow other religions to be followed publicly. There is no problem if you are following any religion within yourself at your home individually. The reason being is that Islam originated from these grounds only. On these grounds are the biggest, oldest and most Holy Mosques of all time and it would be unethical and be a sort of hypocrisy to support other religions when the people of Saudi Arabia are the face of Islam. I personally abide by the fact that they are doing whatever it takes to support and carry forward teaching of their Prophet from thousands of years ago. Without these certain steps, I may not be able to picture Islam to be as prominent as it is now. Things like this have happened in the grounds of Iraq and Iran that were once a ground of Muslims and now only a few are left to carry on.
It is very important to mention here that people can practice their religion in their houses individually. But they are not allowed to hold religious gatherings or establish churches. If you are practicing any religion within yourself, no one is going to take any action against you. There is a vast population of Non-Muslim expatriates living in Saudi Arabia. They are not asked any question if they are practicing their religion within themselves.
Many people often questioned whether tourists are allowed on the grounds of Saudi Arabia. My question here to them would be whether they wish to inquire about tourists who are Muslims or Non-Muslims? This is an important factor that has to be accommodated while traveling to the Kingdom of Saudi Arabia. Of course, Muslims can travel. In fact, every year many Muslims mainly in the shape of Pilgrims from all around the World travel to Saudi Arabia for pilgrimage and to pay a visit to their Prophet's home and the Mosques that He himself established. More importantly, they visit the House of Allah, the Kaaba since it is obligatory for them. For Non-Muslims, however, there are certain restrictions but they are allowed. Many foreigners travel to the Kingdom for business etc. Some travel to join their families during vacation etc. on family visit visas.[irp]
With the mention of businessmen traveling to the Kingdom of Saudi Arabia, I would like to mention and bring about to your notice that the passengers are not allowed to carry with them religious symbols or books other than for their personal uses. They may bring along one cross or one bible with them but not more than that since that will give the picture to the people of Saudi Arabia that you are entering the Kingdom with the intention of converting Muslims to their faith. Such people are questioned by higher authorities. We have also compiled a “List of Prohibited Items to bring (Import) in Saudi Arabia”
I think I've made my thoughts and my knowledge related to this question very clear. A few quick things I would like to mention would include that never talk or disclose about your beliefs in Saudi Arabia especially with someone you don't know. Make sure you keep your beliefs to yourself since you do not know how the citizen might take it as an offense to their laws. It's a Law in the Kingdom of Saudi Arabia that you cannot practice any other religion other than that of Islam so it is best not to question it since it's the best way to stay out of trouble.
