i'll try...i am not willing to translate Qur'an therfor i would quote from the same website.
3:81 And when Allah made a covenant through the prophets: Certainly what I have given you of Book and wisdom-- then an messenger comes to you verifying that which is with you, you must believe in him, and you must aid him. He said: Do you affirm and accept My compact in this (matter)? They said: We do affirm. He said: Then bear witness, and I (too) am of the bearers of witness with you.
3:82 Whoever therefore turns back after this, these it is that are the transgressors.
3:82: Fe men tevellâ ba’de zâlike fe ulâike humul fâsikûn(fâsikûne).
3:83 Is it then other than Allah's religion that they seek (to follow), and to Him submits whoever is in the heavens and the earth, willingly or unwillingly, and to Him shall they be returned.
3:84 Say: We believe in Allah and what has been revealed to us, and what was revealed to Ibrahim and Ismail and Ishaq and Yaqoub and the tribes, and what was given to Musa and Isa and to the prophets from their Lord; we do not make any distinction between any of them, and to Him do we submit
3:85 And whoever desires a religion other than Islam, it shall not be accepted from him, and in the hereafter he shall be one of the losers.
these verses talk about people who Qur'an name as FASIK (Fasikun), it is translated as transgrassors. you do not know what Fasik means. you are a disbeliever but you probably not a FASIK. because FASIK people are the ones who witness messenger of God, they see sign clearly, they believe he is truly messenger of God, they know he is messenger of God. even though they know it they fight against him and they try to keep people away from the truth they personally know. this is what FASIK people do.
