﴿ فَأَقِمْ وَجْهَكَ لِلدِّينِ ٱلْقَيِّمِ مِن قَبْلِ أَن يَأْتِىَ يَوْمٌۭ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ ۖ يَوْمَئِذٍۢ يَصَّدَّعُونَ ﴾

“Set, then, thy face steadfastly towards the one ever-true faith, ere there come from God a Day [of reckoning - the Day] which cannot be averted. On that Day all will be sundered:”

(So set your purpose) set your own self and works (resolutely for the right religion) He says: make your religion and works sincere to Allah, and follow the true, straight religion, (before the inevitable day) which is the Day of Judgement (comes from Allah. On that day) the Day of Judgement (mankind will be sundered) a party of them in Paradise and a party in hell.
