﴿ فَتَوَلَّ عَنْهُمْ ۘ يَوْمَ يَدْعُ ٱلدَّاعِ إِلَىٰ شَىْءٍۢ نُّكُرٍ ﴾

“turn thou away from them. On the Day when the Summoning Voice will sum­mon [man] unto something that the mind cannot conceive,”

(So withdraw from them) so turn away from them, O Muhammad-but he was later commanded to fight them-(on the day) which is the Day of Judgement (when the Summoner summoneth unto a painful thing) a tremendous and frightful thing whereby the dwellers of Paradise will be taken to Paradise and the dwellers of hell to hell.
