^^ Conjecture and hearsay only
As per the Holy Quran, Christians, Jews, Sabians .... all can go to heaven
"Surely, those who believe, those who are the Jews and the Sabians and the Christians – whosoever believed in Allah and the Last Day, and worked righteousness, on them shall be no fear, nor shall they grieve."
[The Holy Quran 5: 69]
“Verily, those who believe and those who are Jews and Christians, and Sabians, whoever believes in Allah and the Last Day and do righteous good deeds shall have their reward with their Lord, on them shall be no fear, nor shall they grieve.” [2: 62]
How do you interpret the verses quoted below? You gave yourself away as soon as you equated the relegation of Qadiyanis as non-Muslims to 'Takfir'.
-----------------------
( 137 ) So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing.
( 138 ) [And say, "Ours is] the religion of Allah. And who is better than Allah in [ordaining] religion? And we are worshippers of Him."
( 139 ) Say, [O Muhammad], "Do you argue with us about Allah while He is our Lord and your Lord? For us are our deeds, and for you are your deeds. And we are sincere [in deed and intention] to Him."
( 140 ) Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allah?" And who is more unjust than one who conceals a testimony he has from Allah? And Allah is not unaware of what you do.
( 141 ) That is a nation which has passed on. It will have [the consequence of] what it earned, and you will have what you have earned. And you will not be asked about what they used to do.
[2:137-141]
------------------------
( 19 ) Indeed, the religion in the sight of Allah is Islam. And those who were given the Scripture did not differ except after knowledge had come to them - out of jealous animosity between themselves. And whoever disbelieves in the verses of Allah, then indeed, Allah is swift in [taking] account.
( 20 ) So if they argue with you, say, "I have submitted myself to Allah [in Islam], and [so have] those who follow me." And say to those who were given the Scripture and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islam], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allah is Seeing of [His] servants.
( 21 ) Those who disbelieve in the signs of Allah and kill the prophets without right and kill those who order justice from among the people - give them tidings of a painful punishment.
( 22 ) They are the ones whose deeds have become worthless in this world and the Hereafter, and for them there will be no helpers.
[3:19-22]
--------------------------
( 84 ) Say, "We have believed in Allah and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him."
( 85 ) And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
