In other words, we go back to square one, rather than saying that the Hebrew bible teaches Islam, we should say that the Qur'an teaches Judaism.
Response: But the teachings and prophethood of Muhammad(pbuh) is not taught in judaism so the qur'an could not be teaching judaism.
But if we look at the examples of the prophets, like Jesus and Moses, we see that the way they pray in the tanakh and the bible is similar to the salaat(prayer) of muslims. Even the jews and christians of today do not follow this example, though their own prophets have. Thus this is another example of Islam taught in the tanakh and the bible.
In the book of numbers 20:6, we read:
"And Moses and Aaron went from the presence of the assembly unto the door of the tabernacle of the congregation, and they fell upon their faces: and the glory of the Lord appeared upon them."
Above we read that Moses and Aaron fell upon their faces when they entered the tabernacle to worship God. I'm asking the question, how did they fall on their faces? From a fall? Not at all. They fell on their faces in the same manner we muslims fall upon ours in salaat through a prostration called "sajdah".
The prophet Moses even made "wudhu". This is the cleansing that muslims do before prayer. In the book of Exodus 40:31-32, we read:
"And Moses and Aaron and his sons washed their hands and their feet thereat:
When they went into the tent of the congregation, and when they came near unto the alter, they washed; as the Lord commanded Moses."
Theses are just a few examples of the teachings of islam even in the tanakh and the bible and shows that islam was the religion of the prophets.
