Surat Al-Anfaal (The Spoils of War) - الأنفال

إِذْ تَسْتَغِيثُونَ رَبَّكُمْ فَٱسْتَجَابَ لَكُمْ أَنِّى مُمِدُّكُم بِأَلْفٍ مِّنَ ٱلْمَلَٰٓئِكَةِ مُرْدِفِينَ ﴿٩﴾ وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشْرَىٰ وَلِتَطْمَئِنَّ بِهِۦ قُلُوبُكُمْ وَمَا ٱلنَّصْرُ إِلَّا مِنْ عِندِ ٱللَّهِ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ﴿١٠﴾

When you sought aid from your Lord, so He answered you: I will assist you with a thousand of the angels following one another. And Allah only gave it as a good news and that your hearts might be at ease thereby; and victory is only from Allah; surely Allah is Mighty, Wise.
