19 But it is right for us to be afraid of the second death, that which is full of weeping and gnashing of teeth, and of groanings and miseries, that which is situated in outer darkness. But blessed shall be the faithful and the righteous in that Resurrection, in which they expect to be awakened and to receive the good promises made them. But as for the wicked who are not faithful, in the Resurrection woe to them, because of that which is laid up for them! It would be better for them according to the faith which they possess, were they not to arise.
For the servant, for whom his Lord is preparing stripes and bonds, while he is sleeping desires not to awake, for he knows that when the dawn shall have come and he shall awake, his Lord will scourge and bind him. But the good servant, to whom his Lord has promised gifts, looks expectantly for the time when dawn shall come and he shall receive presents from his Lord. And even though he is soundly sleeping, in his dream he sees something like what his Lord is about to give him, whatsoever He has promised him, and he rejoices in his dream, and exults, and is gladdened.
As for the wicked, his sleep is not pleasant to him, for he imagines that lo! The dawn has come for him, and his heart is broken in his dream. But the righteous sleep, and their slumber is pleasant to them, in the day-time and the night-time, and they take no thought of all that long night, and like one hour is it accounted in their eyes. Then in the watch of the dawn they awake with joy. But as for the wicked, their sleep lies heavy upon them, and they are like a man who is laid low by a great and deep fever, and tosses on his couch hither and there, and he is terrified the whole night long, which lengthens itself out for him, and he fears the dawn when his Lord will condemn him.
