﴿فَإِنْ خِفْتُمْ فَرِجَالًا أَوْ رُكْبَانًا ۖ فَإِذَا أَمِنْتُمْ فَاذْكُرُوا اللَّهَ كَمَا عَلَّمَكُمْ مَا لَمْ تَكُونُوا تَعْلَمُونَ﴾
239. And if you fear (an enemy), perform Salât (pray) on foot or riding.[2] And when you are in safety, offer the Salât (prayer) in the manner He has taught you, which you knew not (before).
