Then his mind facilitated to him the slaying of his brother so he slew him; then he became one of the losers

And those who believe will say: Are these they who swore by Allah with the most forcible of their oaths that they were most surely with you? Their deeds shall go for nothing, so they shall become losers.

And that was your (evil) thought which you entertained about your Lord that has tumbled you down into perdition, so are you become of the lost ones.
