Surah Ar-Rum (The Romans), Verse 43

فَاَقِمْ وَجْهَكَ لِلدِّیْنِ الْقَیِّمِ مِنْ قَبْلِ اَنْ یَّاْتِیَ یَوْمٌ لَّا مَرَدَّ لَهٗ مِنَ اللّٰهِ یَوْمَىِٕذٍ یَّصَّدَّعُوْنَ ۟

Fa aqim wajhaka lid deenil qaiyimi min qabli any yaatiya Yawmul laa maradda lahoo minal laahi Yawma'iziny yassadda'oon

“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).”
