Did Angels ever come to the help of Muslims according to Quran?
It is pointed out the support of Angels during the battle of Uhud in some of these verses.
For sure God had helped you to victory at Badr when you were a despised (small) force. So observe your duty to God in due reverence for Him, that you may be thankful. When you said to the believers: Does it not suffice you that your Lord will come to your help with three thousand angels sent down? Surely it does. (More than that), if you are steadfast and act in piety to deserve His protection, and the enemy should fall upon you all at once, your Lord will come to your help with five thousand angels swooping down. (Al-Imran Surah, 3:123-125)
God who inform humans about His will (the support of Angels), to prevent believers from getting stuck with Whys and Hows reminds, (1)
God did that only as glad tidings (of your imminent victory), and that your hearts thereby might be at rest. For help and victory come from God alone. Surely God is All-Glorious with irresistible might, All-Wise. (Al-Anfal Surah, 8:10) God did not ordain this save as a message of good hope for you, and so that thereby your hearts might be at peace – victory comes only from God, the All-Glorious with irresistible might, the All-Wise. (Al-Imran Surah, 3:126)
As it is mentioned in the verse, Angels coming to the rescue of believers is because of giving a piece of good news and by this way to make hearts to become tranquil and happy. As He could give, power equal to turn the whole world upside down to an angel,
thousands of Angels appearing in Badr answers the purpose of showing the highness and holiness of this war in a concrete way. (2)
The functions of Angels in Badr is announced as,
When (in the meantime) your Lord revealed to the angels: "I am certainly with you, so make firm the feet of those who believe. I will cast fear into the hearts of those who disbelieve. So strike at their necks and strike at every finger (which holds a sword or bow). (A—Anfal Surah, 8:12)
As it is understood from the verse, angels are intermediators charged with a duty of making believers to gain determination and inspiring fear to non-believers. There are other accounts that inform us about angels charged with a duty in other wars apart from the battle of Badr. In the Independence war of Turkey, in Cyprus peace operation by Turkey of recent date and in the Afghani fighters opposition against Communism, it was reported by many that there had been seen spiritual beings and these spiritual beings had helped Muslims.
