That simply cannot be "re-interpreted".

Interpretations of Sharia—Does It Matter?
Apologists for Islam use desperate methods to make Islam look more attractive. For instance, some support Sharia by saying that Sharia has a long history of reinterpretation and so can be reinterpreted today so it is more compatible with Western law.
Another argument is that there are different schools of Sharia. There are six different schools of Sharia, but all the schools agree on the vast majority of rulings, particularly in dealing with the Kafir.
The problem is that every interpretation must be based on Koran and the Sunna (found in the Sira and the Hadith). For instance, jihad is a large part of the Koran, Sira and Hadith so no matter how many times you reinterpret the Sharia it must include jihad, the jihad of war against the Kafir. Nothing will remove wife beating, FGM, deception of the Kafir, hating the Kafir, and cruel punishments.
We don’t need to reinterpret Sharia; we need to leave it behind.
