Quran 8:9 from Surah Al-Anfaal on Divine Marvels.
إِذۡ تَسۡتَغِيثُونَ رَبَّكُمۡ فَٱسۡتَجَابَ لَكُمۡ أَنِّي مُمِدُّكُم بِأَلۡفٖ مِّنَ ٱلۡمَلَٰٓئِكَةِ مُرۡدِفِينَ
English translation: When you were seeking help (of) your Lord and He answered [to] you Indeed I am going to reinforce you with a thousand of the Angels one after another
Transliteration: idh tastaghithuna rabbakum fa-is'tajaba lakum anni mumiddukum bi-alfin mina al-malaikati mur'difina
