Allah, the Exalted and Most High, says: "And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers." (3:85) "Surely, those who reject Faith (disbelieve in Allah and in Muhammad (saw) as being Allah's Messenger and in all that which he has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide." (3:116) “Say (O Muhammad): “O mankind! Verily, I am sent to you all as the Messenger of Allaah.” (7:158) The Jews and Christians are kuffaar and mushrikeen. Allaah says: “And the Jews say: ‘Uzair (Ezra) is the son of Allaah, and the Christians say: Messiah (Jesus) is the son of Allaah. That is their saying with their mouths, resembling the saying of those who disbelieved aforetime. Allaah’s Curse be on them, how they are deluded away from the truth! … They (Jews and Christians) took their rabbis and their monks to be their lords besides Allaah (by obeying them in things which they made lawful or unlawful according to their own desires without being ordered by Allaah), and (they also took as their Lord) Messiah, son of Maryam (Mary), while they (Jews and Christians) were commanded [in the Tauraat (Torah) and the Injeel (Gospel)] to worship none but One Ilaah (God — Allaah) Laa ilaaha illa Huwa (none has the right to be worshipped but He). Praise and glory be to Him (far above is He) from having the partners they associate (with Him).” (9:30-31) Whoever Says That The Jews Are Not Kaafirs Is Disbelieving In The Words Of Allaah: “And their hearts absorbed (the worship of) the calf because of their disbelief.” (al-Baqarah 2:93) “Among those who are Jews, there are some who displace words from (their) right places and say: “We hear your word (O Muhammad) and disobey,” and “Hear and let you (O Muhammad) hear nothing.” And Raa‘ina [in Arabic it means “Be careful, listen to us, and we listen to you”, whereas in Hebrew, it means “an insult”] with a twist of their tongues and as a mockery of the religion (Islâm). And if only they had said: “We hear and obey”, and “Do make us understand,” it would have been better for them, and more proper; but Allaah has cursed them for their disbelief…” (4:46) “Because of their breaking the covenant, and of their rejecting the Ayaat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allaah, and of their killing the Prophets unjustly, and of their saying: “Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)” — nay, Allaah has set a seal upon their hearts because of their disbelief, so they believe not but a little. And because of their (Jews) disbelief and uttering against Maryam (Mary) a grave false charge (that she has committed illegal sexual intercourse); And because of their saying (in boast), “We killed Messiah ‘Eesaa (Jesus), son of Maryam (Mary), the Messenger of Allaah,” — but they killed him not, nor crucified him, but it appeared so to them the resemblance of ‘Eesaa (Jesus) was put over another man (and they killed that man)]…” (4:155-157) “Verily, those who disbelieve in Allaah and His Messengers and wish to make distinction between Allaah and His Messengers (by believing in Allaah and disbelieving in 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.” (4:150-151) Whoever Says That The Christians Are Not Kuffaar Is Disbelieving In The Words Of Allaah: “Surely, in disbelief are they who say that Allaah is the Messiah (Jesus), son of Maryam (Mary)…” (5:17) “Surely, disbelievers are those who said: “Allaah is the third of the three (in a Trinity).” But there is no Ilaah (god) (none who has the right to be worshipped) but One Ilaah (God —Allâh). And if they cease not from what they say, verily, a painful torment will befall on the disbelievers among them.” (5:73) Abu Huraira (may Allah be pleased with him) has narrated, that our beloved Prophet Muhammad (peace and blessings of Allah be upon him) said: "By Him (Allah) in Whose Hand Muhammad's soul is, there is none from amongst the Jews and the Christians (of these present nations) who hears about me and then dies without believing in the Message with which I have been sent (i.e. Islamic Monotheism), but he will be from the dwellers of the (Hell) Fire." (Sahih Muslim, Book of Faith, Volume 1, Hadith Number 240) The Holy Prophet (sallallahu ‘alayhi wasallam) has also said: "Had Musa (Moses) and Isa (Jesus) (peace be upon them both) been alive, they would have had to follow me." (Fi Zilal al-Quran, Vol. 2) It should be realized that the Law of Prophet Isa (Jesus)(peace be upon him), like the Law of Musa (Moses)(peace be upon him), is now abrogated. And, when Isa, son of Maryam (Mary)(peace be upon them both), returns to this world, he will observe the Law of Muhammad (peace and blessings of Allah be upon him).
