فَإِنْ And if خِفْتُمْ you fear فَرِجَالًا then (pray) on foot أَوْ or رُكْبَانًۭا ۖ riding فَإِذَآ Then when أَمِنتُمْ you are secure فَٱذْكُرُوا۟ then remember ٱللَّهَ Allah كَمَا as عَلَّمَكُم He (has) taught you مَّا what لَمْ not تَكُونُوا۟ you were تَعْلَمُونَ knowing ٢٣٩
And if you fear [an enemy, then pray] on foot or riding. But when you are secure, then remember Allāh [in prayer], as He has taught you that which you did not [previously] know.
