Qur'an 2:256—"There is no compulsion in religion; truly the right way has become clearly distinct from error; therefore, whoever disbelieves in the Shaitan and believes in Allah he indeed has laid hold on the firmest handle, which shall not break off, and Allah is Hearing, Knowing."
(Note: Surah 2 was the first Surah revealed after the Muslims migrated to Medina.)
So many abrogated verses, so little time to convince Westerners that these verses are still relevant to Islam!
Qur'an 2:106—“Whatever communications We abrogate or cause to be forgotten, We bring one better than it or like it. Do you not know that Allah has power over all things?”
Qur'an 16:101—“And when We change (one) communication for (another) communication, and Allah knows best what He reveals, they say: You are only a forger. Nay, most of them do not know.”
Qur’an 9:29—"Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the Religion of Truth, from among the People of the Book, until they pay the Jizyah with willing submission, and feel themselves subdued."
(Note: Sura 9 was one of the last two Surahs revealed, and therefore abrogates any Qur'anic teachings that conflict with it.)
