وَإِذَا And when ضَرَبْتُمْ you travel فِى in ٱلْأَرْضِ the earth فَلَيْسَ then not عَلَيْكُمْ upon you جُنَاحٌ (is) any blame أَن that تَقْصُرُوا۟ you shorten مِنَ [of] ٱلصَّلَوٰةِ the prayer إِنْ if خِفْتُمْ you fear أَن that يَفْتِنَكُمُ (may) harm you ٱلَّذِينَ those who كَفَرُوٓا۟ ۚ disbelieved إِنَّ Indeed ٱلْكَـٰفِرِينَ the disbelievers كَانُوا۟ are لَكُمْ for you عَدُوًّۭا an enemy مُّبِينًۭا open ١٠١
And when you travel throughout the land, there is no blame upon you for shortening the prayer, [especially] if you fear that those who disbelieve may disrupt [or attack] you. Indeed, the disbelievers are ever to you a clear enemy.
