Translation of the verse 32 from Surah Al-MuTaffifin : Number of verses 36 - - page 588 - Part 30.
And when they saw them, they said: "Verily! These have indeed gone astray!"
And when they saw them, they would say, "Indeed, those are truly lost."
(83:32) and when they saw the believers, they said: 'Lo! These are the erring ones'; *13
*13) That is, they have lost their reason: they have deprived themselves of the gains and enjoyments of the world and have experienced dangers and undergone hardships only for the reason that Muhammad (upon whom be Allah's peace and blessings) has deluded them with the Hereafter, Heaven and Hell. They are giving up whatever is present and here on the false hope that the promise of some Paradise has been held out to them after death, and they are enduring the hardships in the present life only for the reason that they have been threatened with some Hell in the next world.
