Q: Based on the Quraan, Allah Ta'ala will not accept any religion other than Islam. And it is in the hadith that if a Christian or a Jew hears about me and didn’t accept Islam and dies as non-Muslim then he will go in Hell forever. I want to ask a few questions.
1. Can a non-Muslim go to heaven? Can a non-Muslim make an excuse to Allah on the Day of Judgment that we were born in a non-Muslim family, so what is our fault if we were born in a Muslim family then we also become Muslim.
2. After the death of Muhammad (sallallahu alaihi wasallam), can a non-Muslim say to Allah Subhanahu wa Ta'ala that no Muslim came to us and he did not preach about Islam and Muhammad (sallallahu alaihi wasallam), so we do not know about Islam. So forgive us. If this is possible so it will apply to all non-Muslims who were born after the death of Muhammad (sallallahu alaihi wasallam).
3. Is teaching Islam to non-Muslims such as Hindus, Christians, and Jews necessary on all Muslims? From my point of view it is very difficult and almost impossible to go to every single non-Muslim and teach Islam in this era. Nowadays, every non-Muslim can find information about Islam through the internet and other social media.
4. Good non-Muslims who serve humanity like mother Teresa or xyz who didn't convert to Islam and died non-muslims, will they go to heaven?
