Hello, I have some very important questions I would very much appreciate if you could answer them, I understand that not everyone or perhaps anyone here is a qualified cleric but please if you know the answer provide as much detail as you can.
1. Where is the method for performing Salat listed? Is it listed in the Quran, In the Hadith or is it an unwritten tradition that has been handed down by previous generations. For instance how do Muslims know how many times to kneel and bow and what to recite and when to recite it, Where is the instructions for the salat methodology listed?
2. Given that Islam believes that Muhammad (PBUH) was the "Seal of the Prophets" what would be the fate of those that lived before the birth of Muhammad (PBUH), For instance those that lived before Muhammad PBUH would have had not idea on the Shahadah since they did not know that Muhammad PBUH was the seal of the prophets nor was the Quran revealed to them, Since these people did not know the Shahadah, where unable to recite the Quran, what would be the fate of these people. I understand that Muslims believe that Muhammad PBUH was the last in a series of prophets.
3. If Allah wanted to reveal the Quran to Muhammad PBUH why then was the Quran dictated to Muhammad PBUH, Via the Angel Gabriel? Why did Allah not simply reveal the Quran directly to Muhammad PBUH?
4. Why was the Qibla (Direction of Prayer) changed from Jerusalem to Mecca? There is almost no information regarding this matter.
