All the Prophets came with one message - One God, Day of Judgement, Paradise and Hell.
So this is why it is OK for a Muslim Men to get married to those who accepted the SAME MESSAGE -from the Prophets that came before them. That God is one.
So when we mean Christians, we don't mean those that say God has taken a son and that they need Jesus as a savior.
Prophet Noah peace be upon him didn't have a different message from Prophet Adam peace be upon him, nor did King David peace be upon him from Prophet Ibrahim peace be upon him.
All Prophets are respected in Islam - we talk of Prophet Muhammad peace be upon him as we benefited from his teachings and the companions at the time listened to his message.
If we didn't have the Prophet Muhammad peace be upon him, then who would have helped us?? Not the Christians for their idol worship and not the Jews who are also changing their text (saying there is no Hell, suicide is OK, that Satan is doing God's job).
It is obvious today we would have been one of the losers.
All the Prophets warned of the test to come -the Dajjal (anti-Christ), no one ever said that God was one of 2, and later will be one of 3-if it was that important of this trinity.
God can only be one -how can there be another God?? When he wouldn't be able to keep his thoughts hidden from the Creator. Also no God is created or dies.
People go to Paradise following the Prophets they followed in life, the most people entering Paradise will be of those following the Prophet Muhammad peace be upon him.
Differences in treatment:
When a Muslim hears one person who followed the Prophets before -you will see them being happy-this is how a believer should accept each other. We are not like the Christians who treat us differently -and they even go so far as say we have a different Creator-so are they saying that the Prophet Moses peace be upon him is a different one to theirs? Is the flood story different one to theirs?? The Jews say they are God's chosen people, the Christians say they are his children and we say we are servants of Allah. The Jews were not happy with the Prophets as message was for all-but they wanted it to work how they wanted in this world. Allah even told Pharoah to repent, even though he killed lots of babies-Allah did not send the plagues of Egypt just to free the Jews-but to serve a sign and tell the evil doers to repent.
Pharoah was so arrogant that he disregarded the message, his arrogance was so important to him, that he did care of the sea parting-he rushed through elevating his own intentions and arrogance. Then he was drowned, but while he was drowning he repented-but this was not accepted as you can't when the punishment comes, his arrogance is not that important, that Allah should move the stars for him etc, for him to see a more sign for him to heed the message.
At the time of Prophet Jesus peace be upon him, people still feared the authorities. Even after the Prophet Jesus peace be upon him came with miracles. Allah gave a table spreadth of food and he said, if those people that received the table came to turn away, he will punish them like he never punished anyone before.
When Prophet Moses peace be upon him killed a guard, he was told, that if this person worshipped him once, that the Prophet would have been in big trouble.
So not everyone is equal -the Prophets come first, the other religious top people, then the religious people and those that include the people who received and accepted the messages beforehand-hence people of the book. So it is impossible to be treated like those who accepted the messages before as a Christian today who does idol worship-looks to be savioured by a Man rather than by Allah.
The Christians tell the Muslims that they were told not to fight at the time of the Prophet Jesus peace be upon him when he was alive. So why are Christians been fighting Muslims etc? When the Prophet Jesus peace be upon him comes back, he will have the Muslims to support him -they will not allow anything to happen to him. We are willing to do what the Christians couldn't do before. The evil doers before threw an arrow to God and God returned it with a blood, allowing the evil doers to believe they killed God-the evil doers fool themselves. They thought they killed Prophet Jesus peace be upon him, but did not, the Christians say body cannot go to Heaven-but his body is in heaven he will be brought down by 2 angels in Damascus.
AS above it is impossible for an idol worshipper to be treated the same as a believer-you wouldn't be allowed in Heaven, no angel even cares about idol worshippers etc or those that refuse to accept God.
Just flimsy saying that you believe in God but don't even regard him or anything of his laws-doesn't not mean you believer-we're not talking of someone you don't think much of, as if they are doing a small job like if htey are picking leaves in the park.
People of the book -believers of the one God, the Day of Judgement, Paradise and Hell. So when the Prophet Muhammad peace be upon him came and even the Jews recognised him (some went there, waiting for a Prophet to come-but as his message was for all, there were those that did not like it). So it is clear, Allah would not be telling the Muslims to get married to someone if they are not going to be cared about by anyone in Heaven-so what is the point, you can't even get the marriage blessed.
Charity is to give the poor their due-it isn't to give them whatever they want. Our lives are not charity, that is why we give to charity. When living with someone is about a religious household, marriage blessed from Allah, so that cannot be with a non-believer.
As above the Christians the Jews have changed their religion, is why this People from the Book isn't the norm. Likewise if a Muslim turns away from Islam, then that marriage is treated as not valid and a divorce is sought.
So, marriage isn't just about personal whims, it is about what is treated as good by Allah and you can hope to be with them in the next world. There is no point of wasting time inputting, when people are not interested in God. Marriage is about helping someone to be good to help pass their test in this world to go into the next.
I don't always spend time online and like to keep to the point, I do stand by those are too basic for someone years down the line -to say they do think God exists- hope for your sake, you sort yourself out, as remember the Prophets told people to repent straightaway, it wasn't we going to sit down and talk about it. They told people to repent or they will go to Hell fire-everyone has a soul and they recognise the truth. As Allah said they reject the truth. Even the homosexuals before as per in the Quran, said this Prophet is telling us to keep "pure"-now it is distorted and dumbed down.
