“When you appealed to your Lord for help, He answered you: ‘I will reinforce you with a thousand angels, coming one after another.’” (9)
“So that He might establish the truth”: that is, so that He might firmly establish Islam. “And abolish falsehood”: that is, destroy disbelief, “even though the criminals”—the polytheists—detest it. The Battle of Badr took place on Friday morning, after seventeen nights of Ramadan had passed.
Allah Most High says, “When you appealed to your Lord for help”: that is, when you sought His protection from your enemy and asked Him for aid and victory.

It is related that Gabriel descended with five hundred and Michael with five hundred, in [the form] (2) of men, riding piebald horses, dressed in white garments and wearing white turbans, whose ends they had let hang between their shoulders (3).
