﴿ إِذْ تَسْتَغِيثُونَ رَبَّكُمْ فَٱسْتَجَابَ لَكُمْ أَنِّى مُمِدُّكُم بِأَلْفٍۢ مِّنَ ٱلْمَلَٰٓئِكَةِ مُرْدِفِينَ ﴾

“Lo! You were praying unto your Sustainer for aid, whereupon He thus responded to you: "I shall, verily, aid you with a thousand angels following one upon' another!"”

(When ye sought help of) when you called upon (your Lord) to assist you on the Day of Badr (and He answered you (saying): I will help you with a thousand of the angels, rank on rank) coming one after another to help you.
