Those who swear allegiance to you indeed swear allegiance to God; and God's protection is over them. Then whosoever breaks the promise breaks it to his own loss; but whosoever fulfills the promise made to God will receive a great reward from Him.
The Arabs of the desert who had stayed behind will now say to you: "We were occupied with our flocks and herds and families, so ask forgiveness for us. They say with their tongues what is not in their hearts. Tell them: "Who can prevail with God for you if He wish you harm or benefit? Surely God is well aware of what you do.
In fact you imagined that the Prophet and the faithful would never come back home; and this seemed pleasing to your hearts, and you entertained evil thoughts. You are a people lost.
He who does not believe in God and His Apostle (should know) We have prepared for unbelievers a blazing fire."
To God belongs the kingdom of the heavens and the earth; He may forgive whosoever He please, and afflict whosoever He will. Yet God is forgiving and kind.
Those who had stayed behind will say: "When you depart for taking the spoils, allow us to follow you." They wish to change the word of God. Tell them: "You will not follow us. That is what God has already said before." They will say: "You are envious of our gain." The fact is they understand but little.
