Allah has already given you victory in many regions and [even] on the day of Hunayn, when your great number pleased you, but it did not avail you at all, and the earth was confining for you with its vastness; then you turned back, fleeing.
The Saheeh International Quran Translation
لَقَدْ نَصَرَكُمُ ٱللَّهُ فِى مَوَاطِنَ كَثِيرَةٍ وَيَوْمَ حُنَيْنٍ إِذْ أَعْجَبَتْكُمْ كَثْرَتُكُمْ فَلَمْ تُغْنِ عَنكُمْ شَيْـًٔا وَضَاقَتْ عَلَيْكُمُ ٱلْأَرْضُ بِمَا رَحُبَتْ ثُمَّ وَلَّيْتُم مُّدْبِرِينَAllah has already given you victory in many regions and [even] on the day of Hunayn, when your great number pleased you, but it did not avail you at all, and the earth was confining for you with its vastness; then you turned back, fleeing.
