[29:57] "Everyone shall taste the death. Then unto Us you shall be returned."
[17:37] "And do not walk upon the earth exultantly. Indeed, you will never tear the earth [apart], and you will never reach the mountains in height."
[66:6] "O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones, over which are [appointed] angels, harsh and severe; they do not disobey Allah in what He commands them but do what they are commanded."
[23:1] "Successful indeed are the believers."
[3:85-87] "Do they seek other than the religion of Allah (the true Islamic Monotheism worshiping none but Allah Alone), while to Him submitted all creatures in the heavens and the earth, willingly or unwillingly. And to Him shall they all be returned.Say (O Muhammad SAW): "We believe in Allah and in what has been sent down to us, and what was sent down to Ibrahim (Abraham), Isma'il (Ishmael), Ishaque (Isaac), Ya'qub (Jacob) and Al-Asbat [the twelve sons of Ya'qub (Jacob)] and what was given to Musa (Moses), 'Iesa (Jesus) and the Prophets from their Lord. We make no distinction between one another among them and to Him (Allah) we have submitted (in Islam)."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."
and who are the "famous" Believers?...
[7:158] "Say, [O Muhammad], "O mankind, indeed I am the Messenger of Allah to you all, [from Him] to whom belongs the dominion of the heavens and the earth. There is no deity except Him; He gives life and causes death." So believe in Allah and His Messenger, the unlettered prophet, who believes in Allah and His words, and follow him that you may be guided."
[24:52] "And whosoever obeys Allah and His Messenger (SAW), fears Allah, and keeps his duty (to Him), such are the successful ones."
So those who are "good" but are disbelievers will it benefit them at the end?...
[39:65] And indeed it has been revealed to you (O Muhammad SAW), as it was to those (Allah's Messengers) before you: "If you join others in worship with Allah, (then) surely (all) your deeds will be in vain, and you will certainly be among the LOSERS."
