Surah Az-Zumar Verse 55 - English Translation by Shabbir Ahmed
Surah Az-Zumarوَٱتَّبِعُوٓاْ أَحۡسَنَ مَآ أُنزِلَ إِلَيۡكُم مِّن رَّبِّكُم مِّن قَبۡلِ أَن يَأۡتِيَكُمُ ٱلۡعَذَابُ بَغۡتَةٗ وَأَنتُمۡ لَا تَشۡعُرُونَ
And follow the best teaching (the Qur'an) that has been revealed for you by your Lord before the doom comes upon you suddenly without your perceiving of the why, how and whence of it. (39:18). (I have rendered: revealed 'for' you instead of 'to' you since the addressee in the verse is plural)
