The Qur'an also says that Jews, Christians (my emphasis), and Sabians, whoever believes in One God, the Day of Judgment, and does good deeds, on them shall be no fear nor shall they grieve.
Verse 2:62 is contrary to the vast majority of those concerning unbelievers. It says,
"Those who believe (in the Qur'an), and those who follow the Jewish (scriptures), and the Christians and the Sabians,- any who believe in Allah and the Last Day, and work righteousness, shall have their reward with their Lord; on them shall be no fear, nor shall they grieve".
If this includes, for example, Christians who believe Jesus to be the son of God, it directly contradicts all previous and future verses such as 29:68 that says,
"And who does more wrong than he who invents a lie against Allah or denies the truth when it comes to him? Is there not a dwelling in Hell for disbelievers". Verse 5:73 is specific to Christians,
"They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them". It could not be more clear.
Also, a clarification (some might say abrogation) of verse 2:62 appears later in 3:199,
"And there are, certainly, among the People of the Book, those who believe in Allah, in the revelation [Qur'an] to you [Mohamed], and in the revelation to them, bowing in humility to Allah: They will not sell the Signs of Allah for a miserable gain". This creates a caveat stating that only those who accept the Qur'an in addition to the Bible have no need to fear, as opposed to
"the People of the Book" in general as 2:62 could be understood to mean.
And Allah from the very beginning, again and again emphasises His Mercy and His Forgiveness. And there is a Hadith Qudsi in which Allah pledges to Himself by writing in His book which is laid down with Him: My Mercy prevails over my Wrath. So clearly He is willing to forgive even those who have gone astray in declaring that He has a son. And Allah knows best.
Again and again Allah claims to be merciful. But, that doesn't comply with the hundreds of verses that promise an eternity of torture by fire for those who do nothing more than reject the religion of islam.
