Quran 3:124 from Surah Aal-i-Imraan on Divine Marvels.
إِذۡ تَقُولُ لِلۡمُؤۡمِنِينَ أَلَن يَكۡفِيَكُمۡ أَن يُمِدَّكُمۡ رَبُّكُم بِثَلَٰثَةِ ءَالَٰفٖ مِّنَ ٱلۡمَلَٰٓئِكَةِ مُنزَلِينَ
English translation: When you said to the believers Is it not enough for you that reinforces you your Lord with three thousand[s] [of] [the] Angels [the ones] sent down
Transliteration: idh taqulu lil'mu'minina alan yakfiyakum an yumiddakum rabbukum bithalathati alafin mina al-malaikati munzalina
