وَلَمَّا بَرَزُواْ لِجَالُوتَ وَجُنُودِهِۦ قَالُواْ رَبَّنَآ أَفۡرِغۡ عَلَيۡنَا صَبۡرٗا وَثَبِّتۡ أَقۡدَامَنَا وَٱنصُرۡنَا عَلَى ٱلۡقَوۡمِ ٱلۡكَٰفِرِينَ

When they advanced to face Goliath and his warriors, they prayed, “Our Lord! Shower us with perseverance, make our steps firm, and give us victory over the disbelieving people.”
