Surah An-Nisa Verse 101 - English Translation by A. J. Arberry
Surah An-Nisaوَإِذَا ضَرَبۡتُمۡ فِي ٱلۡأَرۡضِ فَلَيۡسَ عَلَيۡكُمۡ جُنَاحٌ أَن تَقۡصُرُواْ مِنَ ٱلصَّلَوٰةِ إِنۡ خِفۡتُمۡ أَن يَفۡتِنَكُمُ ٱلَّذِينَ كَفَرُوٓاْۚ إِنَّ ٱلۡكَٰفِرِينَ كَانُواْ لَكُمۡ عَدُوّٗا مُّبِينٗا
And when you are journeying in the land there is no fault in you that you shorten the prayer, if you fear the unbelievers may afflict you; the unbelievers are for you a manifest foe
