It is a necessity to know that more than 1446 years ago the Islam
has been
completed, as Allah, the Exalted, says:
...This day have I perfected your religion for you, completed my favour upon you, and have chosen for you Islam as your religion.... (Quran 5 : 3)
This verse embodies a clear statement that the religion has been completed and so has no need of addition and deletion.
