Ar-Rum - 30:43

فَأَقِمْ وَجْهَكَ لِلدِّينِ الْقَيِّمِ مِن قَبْلِ أَن يَأْتِيَ يَوْمٌ لَّا مَرَدَّ لَهُ مِنَ اللَّهِ يَوْمَئِذٍ يَصَّدَّعُونَ
[30:43]
Then turn thy face straight to the right religion before there come from Allah the day which cannot be averted; on that day they shall become separated.
But set thou thy face to the right Religion before there come from Allah the Day which there is no chance of averting: on that Day shall men be divided (in two).
So set thy purpose resolutely for the right religion, before the inevitable day cometh from Allah. On that day mankind will be sundered-
