The Battle of Badr as a pivotal moment

إِذْ تَسْتَغِيثُونَ رَبَّكُمْ فَٱسْتَجَابَ لَكُمْ أَنِّى مُمِدُّكُم بِأَلْفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُرْدِفِينَ

[Remember] when you were asking help of your Lord, and He answered you, "Indeed, I will reinforce you with a thousand from the angels, following one another."
