Sure 2 Al-Baqarah (The Cow), vers 239

1. فَإِنْ خِفْتُمْ فَرِجَالًا أَوْ رُكْبَانًا ۖ فَإِذَا أَمِنْتُمْ فَاذْكُرُوا اللَّهَ كَمَا عَلَّمَكُمْ مَا لَمْ تَكُونُوا تَعْلَمُونَ

   And if you fear (an enemy, then pray) on foot or riding. But when you are secure, then remember Allah (in prayer), as He has taught you that which you did not (previously) know.

   2:239
