وَمَا كَانَ قَوْلَهُمْ إِلاَّ أَن قَالُواْ ربَّنَا اغْفِرْ لَنَا ذُنُوبَنَا وَإِسْرَافَنَا فِي أَمْرِنَا وَثَبِّتْ أَقْدَامَنَا وانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ
[3:147]
And their saying was no other than that they said: Our Lord! forgive us our faults and our extravagance in our affair and make firm our feet and help us against the unbelieving people.
All that they said was: "Our Lord! Forgive us our sins and anything We may have done that transgressed our duty: Establish our feet firmly, and help us against those that resist Faith."
Their cry was only that they said: Our Lord! forgive us for our sins and wasted efforts, make our foothold sure, and give us victory over the disbelieving folk.
