Quran 2:58

وَإِذۡ قُلۡنَا ٱدۡخُلُواْ هَـٰذِهِ ٱلۡقَرۡيَةَ فَڪُلُواْ مِنۡهَا حَيۡثُ شِئۡتُمۡ رَغَدً۬ا وَٱدۡخُلُواْ ٱلۡبَابَ سُجَّدً۬ا وَقُولُواْ حِطَّةٌ۬ نَّغۡفِرۡ لَكُمۡ خَطَـٰيَـٰكُمۡ‌ۚ وَسَنَزِيدُ ٱلۡمُحۡسِنِينَ ٥٨

Recall that we said, "Enter this town, where you will find as many provisions as you like. Just enter the gate humbly, and treat the people nicely. We will then forgive your sins, and increase the reward for the pious."
