What About those who do not Accept Islam but do good deeds and are kind people ?
1. The disbelievers are in Hell forever:
"Those who disbelieve and die as disbelievers, on them is the Curse of Allaah, the curse of the Angels and all of mankind. They will abide therein and their penalty will never be lightened nor will they be given respite." [2:161-162]
"Thus Allaah will show them their deeds as regrets and they will never leave the Fire." [2:167]
"Every time they seek to get away therefrom, from anguish they will be driven back therein and it will be said: 'taste the torment of burning'." [22:22]
2. The Christians are disbelievers:
"Indeed they disbelieved who say that Allaah is Christ." [5:17]
"Indeed they disbelieved who say that Allaah is Christ the son of Mary. But the Messiah, son of Mary said, 'O Children of Israel! Worship Allaah, my Lord and your Lord.' Indeed whosoever sets up partners with Allaah then Allaah has forbidden Paradise for him and the Fire shall be his abode. And for the wrong-doers there are no helpers. Surely they disbelieve who said that Allaah is the third of three but there is no god save one god." [5:72-73]
"The Christians say: Messiah is the son of Allaah. They imitate the saying of the disbelievers of old, Allaahs curse be on them how they are deluded away from the truth."
Yes, whosoever believes in Allaah and the Last Day is a Muslim, but can the Christians be said to believe in Allaah? No! Instead they insult Him in the worst of ways and in fact worship something that is not Allaah but a mere figment of their imagination.
As for Christian X being worse or better than Abu Jahl then this is for Allaah and not for us to decide, it is for us to judge on what is outward and as for what is inside a person then that is for Allaah to judge.
3. Their actions are null and void:
"Whosoever rejects faith then his deeds are fruitless and in the Hereafter he will be from the losers." [5:5]
"As for those who disbelieve then their deeds are like a mirage in the desert, The thirsty one thinks it to be water until he comes up to it and finds nothing but he finds Allaah with him Who will pay him his due (in Hell)." [24:39]
4. The necessity of testifying to the Messengership of Muhammad (sallallaahu ’alayhi wa sallam) to become a Muslim:
"When the hypocrites come to you (O Muhammad) they say: We bear witness that you are the Messenger of Allaah. Allaah knows that you are indeed His Messenger and Allaah bears witness that the Hypocrites are indeed liars." [63:1]
Who is and who is not a hypocrite is known to Allaah Alone. We are just ordered to judge on what is outward, therefore whosoever says the shahaadah then he is a Muslim as far as we [Ahlus Sunnah] are concerned and by virtue of his saying the shahaadah he is better than the best of the disbelievers.
"Say (O Muhammad): If you truly love Allaah then follow me. Allaah will forgive you your sins and Allaah is Oft Forgiving and Most Merciful." [3:31]
The Messenger of Allaah (sallallaahu ’alayhi wa sallam) said to Mu`aadh, "your are going to a community of the People of the Book so first call them to testify that there is none worthy of worship save Allaah and that I am the Messenger of Allaah…" [Saheeh Muslim no. 27]
He (sallallaahu ’alayhi wa sallam) also said, "I have been commanded to fight the people until they testify that none has the right to be worshipped save Allaah and that I am the Messenger of Allaah…." [Saheeh Muslim no. 31]
The Messenger of Allaah (sallallaahu ’alayhi wa sallam) said, "I bear witness that none has the right to be worshipped save Allaah and that I am the Messenger of Allaah. The man who meets his Lord without harboring doubt about any of these two would never be kept away from Paradise." [Saheeh Muslim no. 42]
The Messenger of Allaah (sallallaahu ’alayhi wa sallam)) said, "He who testifies that there is none worthy of worship save Allaah and that Muhammad is His servant and Messenger and that Christ is His servant and the son of His slave-girl (Mary) and he is a word which He communicated to Mary and His spirit and that Paradise is a fact and that Hell is a fact. Allaah would make him enter Paradise through any of its eight doors that he wishes." [Saheeh Muslim no. 43]
Whosoever does not testify to the Messengership of Muhammad (sallallaahu ’alayhi wa sallam) has not believed in Allaah correctly and in fact he has rejected all the Prophets for to reject one it to reject all.
5. It is obligatory upon the one who hears of Islaam to accept it:
The Messenger of Allaah (sallallaahu ’alayhi wa sallam) said, "by Him in Whose hand is the life of Muhammad whosoever from the Jews and Christians hears about me and does not believe in me and what I have come with shall be one of the denizens of the Fire." [Saheeh Muslim no. 284]
6. The Jewish and Christian religions are abrogated and invalid:
"Fight against those who believe not in Allaah nor the Last Day nor forbid that which Allaah and His Messenger have forbidden and those who do not acknowledge the Religion of Truth from amongst the People of the Book until they pay jizya with willing submission and feel themselves subdued." [9:29]
"Indeed the only religion (acceptable) with Allaah is Islaam." [3:19]
"And whosoever seeks a religion other than Islaam it will never be accepted of Him and in the Hereafter he will be of the losers." [3:85]
"This day have I perfected your religion for you, completed My Favor upon you and have chosen for you Islaam as your religion." [5:3]
"And We have sent to you the Book confirming the Scripture that came before it and a witness over it." [5:48]
And Allaah the Most High knows best
