Greetings in Christ, Hamdi Ahmed.
First,
welcome to CF! I am overjoyed to know of your openness to Christianity, and I hope that we here can help you in whatever way so that you can get answers to your questions.
We have a fellow Saudi believer here on CF who you might be interested to talk to. He goes by
@Al Masihi , and I imagine he would be very understanding of the cultural issues surrounding conversion to Christianity from a Muslim background. This forum can be a safe place to discuss such things, if you wish.
And I agree with the others about reading the Holy Bible. In my Church we use Arabic in the readings since the 13th century AD, when Arabic replaced Coptic as the language of the Egyptian people. So you can find the Bible in Arabic online at many places.
Here is a Coptic Orthodox website that has the Bible in Arabic as well as English.
In addition to this, in Orthodox Christianity, we have a daily prayer routine that might feel a little bit familiar to you as a Muslim, except we pray 7 times a day, not 5. The 7 hours of prayer correspond to times of day from sunrise to sunset, and each has its meaning within the life of Christ and of the Church. The book that we use for the prayers in the Egyptian Church, which are mostly taken from the Psalms of the Holy Bible, is called the Agpeya, which comes from the Coptic word meaning "hour".
Here it is in Arabic, and
here it is in English.
The way we pray in Orthodoxy might also seem familiar to you, as it involves prostration/sujud as well, which is a practice that we probably carried over from Judaism. (There are many other outward similarities with Islam in Orthodoxy as well, such as fasting for a long period of time; the crucial differences of course are in theology and spiritual approach.)
Here is an Orthodox monk explaining in English to some Russian tourists how we prostrate ourselves and what it means:
Please feel free to ask any questions you may have. I understand it must be very hard to be from a country that has no churches that you can attend, but hopefully you may travel at some point and attend a church in a nearby country like in the Levant or in North Africa. May God be with you and guide you in all things. Lord have mercy.
