Sura 30 Ar-Rum (The Romans), ayah 43

1. فَأَقِمْ وَجْهَكَ لِلدِّينِ الْقَيِّمِ مِنْ قَبْلِ أَنْ يَأْتِيَ يَوْمٌ لَا مَرَدَّ لَهُ مِنَ اللَّهِ ۖ يَوْمَئِذٍ يَصَّدَّعُونَ

   So direct your face toward the correct religion before a Day comes from Allah of which there is no repelling. That Day, they will be divided.

   30:43
