Islam is NOT about "Ïslam is better than your religion"
Islam IS "Let me show you something BETTER for you"
If you follow, it will be good for you. If you do not follow, then you are the one who will be at loss.
With this statement is the dakwah to non-Muslim.
If they follow us, well and good
If they do not follow us, truly we have done our obligation to show them something special and they do not want it. Give your best.. and leave the rest (to Allah)
Ya Rabb, make us ALL Muslims and invite us to enter your jannah
