Hey guys,
The answer is actually very simple. When we muslims pray 5 times a day, what we say or recite is the Holy Qur'an in arabic. Like when we are standing up, we are reciting different parts of the Qur'an. EVERY muslim MUST recite surah fatiha or Chapter 1 (the openng) when they stand up. Then they have to recite another chapter or parts of a chapter. There are a total of 114 chapters in the Qur'an. After they recite a second chapter or part of a chapter, they bow down and prostrate saying things like "Allah/God is above all". When the muslim is sitting on the ground, they also recite things in arabic but i am pretty sure that is not Qur'an. Rather it is more of supplication type. And when we are done praying, we turn our heads to the right and left each time saying "may peace be upon you" to whomever is on our right and left. Everyting in the prayer has to be in arabic.
For those who have difficulties with the language and pronounciation, well they arent alone. I have very bad pronounciation and i know that, but I still have to try. Its definitely a stuggle but you give it your all. And we should always make dua (supplication) to God for Him to make it easy on us.
Acutally i was kind of laughing when i heard some of your comments. Especially the one where we curse out other religions. This is so untrue. This is another reason why so many people memorized the Qur'an in arabic to its entirety. Because we have to recite it for every prayer.
I hope this helped clear up things.
