124إِذْ تَقُولُ لِلْمُؤْمِنِينَ أَلَن يَكْفِيَكُمْ أَن يُمِدَّكُمْ رَبُّكُم بِثَلَـٰثَةِ ءَالَـٰفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُنزَلِينَ
125بَلَىٰٓ ۚ إِن تَصْبِرُوا۟ وَتَتَّقُوا۟ وَيَأْتُوكُم مِّن فَوْرِهِمْ هَـٰذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ ءَالَـٰفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُسَوِّمِينَ
126وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشْرَىٰ لَكُمْ وَلِتَطْمَئِنَّ قُلُوبُكُم بِهِۦ ۗ وَمَا ٱلنَّصْرُ إِلَّا مِنْ عِندِ ٱللَّهِ ٱلْعَزِيزِ ٱلْحَكِيمِ
127لِيَقْطَعَ طَرَفًا مِّنَ ٱلَّذِينَ كَفَرُوٓا۟ أَوْ يَكْبِتَهُمْ فَيَنقَلِبُوا۟ خَآئِبِينَ
[124-127] Remember when you said to the Believers, "Does it not suffice you that Allah should help you by sending down three thousand angels?"96 -Yes, if you show fortitude and fear Allah in whatever you do, Allah will help you with (not three thousand but) five thousand angels, known by certain marks, in case of a sudden attack from the enemy. Allah has told you this so that you may rejoice and your hearts be filled with peace: victory and succour come from Allah alone, Who is All-Powerful, All-Wise. (He will succour you) so that He may cut off a flank of the disbelievers or put them to rout with dishonour.
96The Holy Prophet heartened the Muslims with this promise when they were disheartened to confront an army of 3,000 men with a small army of 1,000 which was further reduced to 700 men by the desertion of 300 hypocrites.
