وَإِذَا ضَرَبۡتُمۡ فِي ٱلۡأَرۡضِ فَلَيۡسَ عَلَيۡكُمۡ جُنَاحٌ أَن تَقۡصُرُواْ مِنَ ٱلصَّلَوٰةِ إِنۡ خِفۡتُمۡ أَن يَفۡتِنَكُمُ ٱلَّذِينَ كَفَرُوٓاْۚ إِنَّ ٱلۡكَٰفِرِينَ كَانُواْ لَكُمۡ عَدُوّٗا مُّبِينٗا
Rowwad Translation Center
When you are traveling through the land, there is no blame on you to shorten the prayer[1], if you fear that the disbelievers may harm you[2]. Indeed, the disbelievers are your open enemy.
Notes
[1] Four rak‘ah prayers are shortened to two rak‘ahs.
[2] Fear is not a condition for this concession, merely travel.
