And if ye go in fear, then (pray) standing or on horseback. And when ye are again in safety, remember Allah, as He hath taught you that which (heretofore) ye knew not.

محمد جالندھری
اگر تم خوف کی حالت میں ہو تو پیادے یا سوار (جس حال میں ہو نماز پڑھ لو) پھر جب امن (واطمینان) ہوجائے تو جس طریق سے خدا نے تم کو سکھایا ہے جو تم پہلے نہیں جانتے تھے خدا کو یاد کرو
