I feel regret for sin. i had sex with my girlfriend and was almost closure to an intercourse. my penis was into her vagina partially(inserted about half and it is for a very short period of time) and it was separated by a thin cloth(her pants, as she didn't removed her pants intentionally to evade the punsihment from God ). Does it considered as a fornication according to Sharia, if not what is the punishment for my mistake. and kindly define fornication according to Sharia
Whether this was considered an intercourse or not. There is no doubt that you had gone extremely far in exceeding the boundary of Allah. In Qur'an, Allah warned Muslim from even going near fornication. Therefore you must repent to Allah sincerely and honestly.
There is no doubt that Allah forgives all sins.
Once you have repented to Allah sincerely then you should move on with your life and make sure that you do not repeat this mistake again.
And Allah knows best.
