The Coalition - 33:23
There are such of the believers who have fulfilled their promise to Allah. Some of them fulfilled their pledge (became martyrs) and some of them are waiting. They have never wavered.
The believers' pledge of allegiance in battle:
The Coalition/33:15
They had promised Allah before that they would not turn their backs and flee. Every promise made to Allah will be questioned.
The Victory/48:10
Those who pledge allegiance to you have pledged allegiance to Allah. Allah´s hand is upon their hands. Whoever breaks his pledge breaks it against himself. And whoever fulfills his promise to Allah, We shall give him a great reward.
The Victory/48:18
Allah is pleased with the believers who pledged allegiance to you under the tree. He knew what was in their hearts and sent down peace on them and rewarded them with an imminent victory.
