The Quran does say to force people to convert to Islam. The verses that say there is to be no compulsion in religion were
abrogated, that means they no longer stand, because they were replaced by the later verses which compel Muslims to force Islam on non-believers. The Medina-era Surahs are peaceful, but were later replace by the violent Mecca-era Surahs. The contrast between the Medina-era Mohammed versus Mecca-era Muhammed are crucial to understanding the abrogation of peaceful Surahs.
“When speaking with people of Christianized/Western societies, Muslim activists
deliberately hide a major Islamic doctrine called “
al-Nasikh wal-Mansoukh” (
the Abrogator and the Abrogated). This simply means that in situations wherein verses contradict one another,
the early verses are overridden by the latter verses. The chronological timing in which a verse was written determines its authority to establish policies within Islam. Non-Muslims cannot afford to be ignorant about the full implications of the
Abrogator and the Abrogated Doctrine (al-Nasikh wal-Mansoukh).
When Islamic spokesmen say that Islam is a religion of peace and that the Quran does not support such things as human rights infractions, gender bias and terrorism, they are lying. This means that the Western politicians and liberal journalists, who continually spout that Islam is a noble religion of peace, are in reality propagating a deception that they have been deceived into parroting.”
The verse that Abrogated (nullified) the Peace Verses.
An example of the abrogation: There are 124 versus that call for tolerance and patience that have been cancelled and replaced by one, single verse. This verse is called the verse of the sword:
"But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, and seize them, beleaguer them, and lie in wait for them in every stratagem (of war)…" Surah 9:5
The peaceful Surahs which were abrogated by Surah 9:5 are listed on this site:
