فَسِيحُوا۟ فِى ٱلْأَرْضِ أَرْبَعَةَ أَشْهُرٍۢ وَٱعْلَمُوٓا۟ أَنَّكُمْ غَيْرُ مُعْجِزِى ٱللَّهِ ۙ وَأَنَّ ٱللَّهَ مُخْزِى ٱلْكَٰفِرِينَ
How to read it
Fassīḥū fī l-'ar'ḍi 'ar'baʻata 'ash'hurin wa-ʻ'lamū 'annakum' ghay'ru muʻ'jizī -llahi wa'anna -llaha mukh'zī l-kāfirīna
Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land, but know ye that ye cannot frustrate Allah (by your falsehood) but that Allah will cover with shame those who reject Him.
Translation: Abdullah Yusuf Ali
