Believer or Kaafir

🔥 A Person is either a Mu’min (Believer) or a Kaafir (the one having no Imaan), and there is no in between.

Allaah تعالى says:
هُوَ الَّذِي خَلَقَكُمْ فَمِنكُمْ كَافِرٌ وَمِنكُم مُّؤْمِنٌ ۚ وَاللَّـهُ بِمَا تَعْمَلُونَ بَصِيرٌ
“He it is Who created you, then some of you are disbelievers and some of you are believers. And Allaah is All-Seer of what you do.” [Surah al-Taghaabun (64):2]

Any person who does not accept Islaam as his religion or opposes it is a Kaafir, irrespective of if he is a Christian, Jew, Buddhist, or a Magian.

But the moment the word Kaafir is mentioned, some people start believing that we are damning them to Hell. What they fail to realize is that there are two issues involved here:
1) Treating them as Kaafir.
2) Damning them to Hell.

🌟 Part 1: Treating them as Kaafir:
This is part of the worldly affairs and which is again sub-divided into what a Muslim can do and what he cannot:
🔴 A) What a Muslim can’t do (amongst them are):
🚫 a) A Muslim cannot eat their slaughter (with the exception in the case of the Jews & the Christians).
🚫 b) A Muslim cannot marry their women (again with the exception in the case of the Jews & the Christians).
🚫 c) They cannot marry Muslim women.
🚫 d) A Muslim cannot inherit from a Kaafir.
🚫 e) A Kaafir cannot inherit from a Muslim.
🚫 f) A Muslim cannot pray for their forgiveness.
🚫 g) They are not allowed to be buried in the Muslim cemetery.
🚫 h) A Muslim cannot say “Allaah have mercy on you”, when they sneeze.

🔵 B) But what a Muslim can do:
✔ a) Give them their rights, especially the rights of the neighbors, even if he/she is a Kaafir.
✔ b) Give them gifts or receive gifts from them (but avoid receiving or giving gifts on the days of their festivities like Christmas etc.)
✔ c) Teach them about Islaam.
✔ d) Supplicate to Allaah for their guidance.
✔ e) Send them food etc.
So these are all from the worldly affairs.

🌟 Part 2: Damning them to Hell:
As for individuals, then we do not and we cannot say anything about individuals (i.e. so-and-so is in Jannah or so-and-so is in Jahannum) except as has been mentioned in the Book of Allaah and the Sunnah of His Messenger صلى الله عليه وسلم.
This matter is related with the Hereafter and Allaah will judge us and them and settle our affairs accordingly. Allaah, in his Devine Wisdom, will deal with everyone with Justice. Those who did not receive the Message will be tested on that Day as has been affirmed by the scholars through various textual evidences.

🍁So you see, the issue is clear regarding their affairs in this world and that of the Hereafter.
