insulting mode, not acceptable and absolutely wrong.

Once you accept the faith then you could revert from all your present / past sins and ask for Allah's mercy and forgiveness for your misdeeds.
Once you feel ashamed, he is always ready to forgive you.
Ask for his mercy anytime before you Die.

Gypsy: Noways, a woman will go to hell, just she didn't wear a veil or celebrate valentines day.

After accepting Islam, InshaAllah, you are cleaned from all your sins LIKE you have born TODAY and your heart will start liking all HIS instructions, whatever Allah prefered and liked for you.

All muslims final destination is Heaven (jannah) But due to our sins we will see hell as well....
"May Allah forbid Hell on us and give us His Forgiveness and Mercy for our Sins we committed knowingly and unknowingly....Ameen"

Definitely, muslims will get punished for their wrong doings and get cleaned before they send to Jannah.

I believe and agree to all commands of Allah and follow as much as possible, whatever we are unable to do due to my own weaknesses, we ask for His mercy and forgiveness.
