You wrote: “(10:87:1) wa-awḥaynā And We inspired = Revelataion from Allah, before they left Egypt”
Are you really in sound state of mind? You are using the first three words in 10:87 and neglecting all that followed this? The revelations from Allah are in the remaining part of the same verse. Here is that revelation:
10:87: And We inspired to Moses and his brother, "Settle your people in Egypt in houses and make your houses [facing the] qiblah and establish prayer and give good tidings to the believers."
Is the above part of Taurat? Obviously not.
