In chapter 2:62 we read:
VERILY, those who have attained to faith [in this divine writ], as well as those who follow the Jewish faith, and the Christians, and the Sabians -all who believe in God and the Last Day and do righteous deeds-shall have their reward with their Sust; and no fear need they have, and neither shall they grieve.
Then in 98:6 chapter we read:
Verily, those who disbelieve from among the people of the Scripture and (from among) those who associate gods with God shall be consigned to the Fire of Gehenna. Therein they shall abide. It is they who are the worst of all creatures.
How do you reconcile the two? Moreover, does this not negate plurality of belief as we read in 5:48:
And unto thee [O Prophet] have We vouchsafed this divine writ, setting forth the truth, confirming the truth of whatever there still remains of earlier revelations and determining what is true therein. Judge, then, between the followers of earlier revelation in accordance with what God has bestowed from on high, and do not follow their errant views, forsaking the truth that has come unto thee. Unto every one of you have We appointed a [different] law and way of life. And if God had so willed, He could surely have made you all one single community: but [He willed it otherwise] in order to test you by means of what He has vouchsafed unto, you. Vie, then, with one another in doing good works! Unto God you all must return; and then He will make you truly understand all that on which you were wont to differ.
On a side note, some Muslims who believe in the theory of abrogation, are quick to defend the above as "Verse A contradicts verses B and C".
However, I am sure there must be a better explanation.
