Wa Alaikum As'salam dear brother,
Everything regarding the abrogation lie on Islam and also abrogation in the Bible is found at:
www.answering-christianity.com/abrogation.htmFeel free to post all of your questions and concerns, akhi. The conjecture that Muslims so ridiculously do regarding this topic is not acceptable. They themselves can't even agree on the bogus claims that they utter. Some say the Noble Verses that were abrogated were in the 10s. Others say in the 100s.
Take care,
Osama Abdallah
