But if this is true this means that Allah cannot be ‘all powerful’ because at some point in the past he revealed the Old Testament (Torah) and the New Testament (Injeel) through the prophets but was not powerful enough to keep it pure through correct transcription and translation. At some point Allah became very weak and some evil men were able to overpower his Word.
Sorry, I love and respect my Muslim friends and I’m reading the Koran, but this does not make sense! Allah cannot be all powerful and at the same time have his word changed or destroyed by human beings.
