It helps the readers now and in the future if you provide the scripture to which you are basing your statement.
hi wil
it's all in that link provided couple posts above; also here's a few more:
The following verse is very clear in that it says the Prophet Muhammad pbuh came with new laws (I.e, the Quran) for Jews and Christians and only those out of them who believe in him, follow him, they will be saved
"Those who follow the Messenger, the Prophet who can neither read not write whom they find written with them in the Tawraat and the Injeel, - he commands them for al-Ma’roof (i.e., Islamic monotheism and all that Islaam has ordained); and forbids them from al-Munkar (i.e., disbelief, polytheism of all kinds, and all that Islaam has forbidden); he allows them as lawful al-Tayyibaat (i.e., all good and lawful as regards things, deeds, beliefs, persons, foods, etc.), and prohibits them as unlawful al-khabaa’ith (i.e., all evil and unlawful as regards things, deeds, beliefs, persons, foods, etc.), he releases them from their heavy burdens (of Allaah’s Covenant) and from the fetters (bindings) that were upon them. So those who believe in him (Muhammad), honor him, help him and follow the light (the Qur’aan) which has been sent down with him, it is they who will be successful."
[al-A’raaf 7:157]
Believe ye in part of the Scripture and disbelieve ye in part thereof? And what is the reward of those who do so save ignominy in the life of the world, and on the Day of Resurrection they will be consigned to the most grievous doom. For Allah is not unaware of what ye do. (2:85)
And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve. But those who reject Our
ayat (verses, signs, proofs), the torment will touch them for their disbelief. (
Al-An`am 6:48, 49)
Verily, those who disbelieve in Allah and His Messengers and wish to make distinction between Allah and His Messengers saying, ‘We believe in some but reject others,’ and wish to adopt a way in between. They are in truth disbelievers. And We have prepared for the disbelievers a humiliating torment. (
An-Nisaa’ 4:150, 151)
above verse clarifies ALL of God's Messengers (including Prophet Muhammad pbuh) must be believed and accepted as God's Messengers or otherwise you're not a believer and will be in hell
