The Spoils of War
إِذْ تَسْتَغِيثُونَ رَبَّكُمْ فَٱسْتَجَابَ لَكُمْ أَنِّى مُمِدُّكُم بِأَلْفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُرْدِفِينَ
[Remember] when you asked help of your Lord, and He answered you, "Indeed, I will reinforce you with a thousand from the angels, following one another."

وَإِذْ يَعِدُكُمُ ٱللَّهُ إِحْدَى ٱلطَّآئِفَتَيْنِ أَنَّهَا لَكُمْ وَتَوَدُّونَ أَنَّ غَيْرَ ذَاتِ ٱلشَّوْكَةِ تَكُونُ لَكُمْ وَيُرِيدُ ٱللَّهُ أَن يُحِقَّ ٱلْحَقَّ بِكَلِمَـٰتِهِۦ وَيَقْطَعَ دَابِرَ ٱلْكَـٰفِرِينَ
[Remember, O believers], when Allah promised you one of the two groups - that it would be yours - and you wished that the unarmed one would be yours. But Allah intended to establish the truth by His words and to eliminate the disbelievers
لِيُحِقَّ ٱلْحَقَّ وَيُبْطِلَ ٱلْبَـٰطِلَ وَلَوْ كَرِهَ ٱلْمُجْرِمُونَ
That He should establish the truth and abolish falsehood, even if the criminals disliked it.
وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشْرَىٰ وَلِتَطْمَئِنَّ بِهِۦ قُلُوبُكُمْ ۚ وَمَا ٱلنَّصْرُ إِلَّا مِنْ عِندِ ٱللَّهِ ۚ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ
And Allah made it not but good tidings and so that your hearts would be assured thereby. And victory is not but from Allah. Indeed, Allah is Exalted in Might and Wise.
إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةً مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءً لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَـٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ
[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet.
