That's the distinction between religions. I am not acting a religious missionary here. Did I say join Islam if want to go to heaven?
If you have more questions or doubts, feel free to ask.
Explanation:
As already explained briefly in the opening remarks, the verse 191, that is, وَاقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم (And kill them; wherever you find them and drive them out from where they drove you out...), was revealed after the happening at Hudaybiyyah حُدیبیہ at a time when the Holy Prophet ﷺ decided, in accordance with the condition agreed upon in the Peace Treaty of Hudaybiyyah حُدیبیہ ، to embark on a journey to Makkah to perform the qada' قضاء of ` Umrah along with his Companions, something he was stopped from doing a year before by the disbelievers of Makkah. The noble Companions ؓ ، on the eve of this projected journey,
had started to worry about the disbelievers who could not be trusted upon in a peace treaty. If they chose to be aggressive, as they did a year before, what option are they going to take? Thereupon, the words used in the present verse gave them the permission to meet the challenge of their aggression and kill them where they find them. And if they could,
it was permissible for them to drive the disbelievers out from where they had driven the believers out.
And I have been reading Quran since I was 8-9 years old, or maybe even younger than this.
