were saying to the believers, “Is it not sufficient for you that your Lord should reinforce you with three thousand angels sent down?
Yea, if you are patient and fear, and they come against you instantly, your Lord will reinforce you with five thousand angels accoutred.”
The tranquility sent by the Real (سبحانه) to the heart of MuṣṬafā ﷺ was from God (سبحانه), without intermediary, while the strengthening of the hearts of the believers was through the intermediary of the Messenger ﷺ. If not for [the doubt that] remained in them, he would not have replied to them, telling [them] of the help [that would] be sent in the angel (malak). Why tell of the angel when the affair is entirely in the hand of the King (malik)?
