﴿ لَقَدْ نَصَرَكُمُ ٱللَّهُ فِى مَوَاطِنَ كَثِيرَةٍۢ ۙ وَيَوْمَ حُنَيْنٍ ۙ إِذْ أَعْجَبَتْكُمْ كَثْرَتُكُمْ فَلَمْ تُغْنِ عَنكُمْ شَيْـًۭٔا وَضَاقَتْ عَلَيْكُمُ ٱلْأَرْضُ بِمَا رَحُبَتْ ثُمَّ وَلَّيْتُم مُّدْبِرِينَ ﴾

“Indeed, God has succoured you on many battlefields, [when you were few;] and [He did so, too,] on the Day of Hunayn, when you took pride in your great numbers and they proved of no avail whatever to you -for the earth, despite all its vastness, became [too] narrow for you and you turned back, retreating:”

(Allah hath given you victory on many fields) on many battlefields (and on the day of Hunayn) and especially on the day of Hunayn, a valley between Mecca and Ta'if, (when ye exulted in your multitude) when you were pleased by your sheer numbers. They were then 10,000 men (but it availed you naught) but your multitude did not prevent your defeat, (and the earth, vast as it is, was straitened for you) because of fear; (then ye turned back in flight) from the enemy, who consisted of 4,000 men;
