9:44Those who believe in God and the Last Day do not ask you for exemption from striving with their possessions and their lives. God is fully aware of the righteous.

9:45Only those who do not believe in God and the Last Day ask you for exemption. Their hearts are full of doubts, so they waver in their doubts.

9:86When a chapter is revealed, stating: “Believe in God and strive with His Messenger,” the prominent among them ask you for exemption. They say, “Allow us to stay with those who stay behind.”

9:90Some of the Desert-Arabs came to make excuses, asking to be granted exemption, while those who were untrue to God and His Messenger stayed behind. A painful punishment will afflict those among them who disbelieved.

9:93But blame is on those who ask you for exemption, although they are rich. They are content to be with those who stay behind. God has sealed their hearts, so they do not know.
