The Cow 2:250. Juz 2, page 41.
وَلَمَّا بَرَزُوا۟ لِجَالُوتَ وَجُنُودِهِۦ قَالُوا۟ رَبَّنَآ أَفْرِغْ عَلَيْنَا صَبْرًا وَثَبِّتْ أَقْدَامَنَا وَٱنصُرْنَا عَلَى ٱلْقَوْمِ ٱلْكَـٰفِرِينَ٢٥٠And when they went into the field against Goliath and his hosts they said: Our Lord! Bestow on us endurance, make our foothold sure, and give us help against the disbelieving folk.
