Al-Anfal - 8:9

إِذْ تَسْتَغِيثُونَ رَبَّكُمْ فَاسْتَجَابَ لَكُمْ أَنِّي مُمِدُّكُم بِأَلْفٍ مِّنَ الْمَلآئِكَةِ مُرْدِفِينَ
[8:9]
When you sought aid from your Lord, so He answered you: I will assist you with a thousand of the angels following one another.
Remember ye implored the assistance of your Lord, and He answered you: "I will assist you with a thousand of the angels, ranks on ranks."
When ye sought help of your Lord and He answered you (saying): I will help you with a thousand of the angels, rank on rank.
