9 verses have
gain
in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:4Except for those among the polytheists with whom you had made a treaty, and did not violate any of its terms, nor aided anyone against you. So fulfill the treaty with them to the end of its term. God loves the righteous.

9:13Will you not fight a people who violated their oaths, and planned to exile the Messenger, and initiated hostilities against you? Do you fear them? It is God you should fear, if you are believers.

9:14Fight them. God will punish them at your hands, and humiliate them, and help you against them, and heal the hearts of a believing people.

9:42Had the gain been immediate, and the journey shorter, they would have followed you; but the distance seemed too long for them. Still they swear by God: “Had we been able, we would have marched out with you.” They damn their own souls, and God knows that they are lying.

9:48They tried to cause conflict before, and they hatched plots against you, until the truth prevailed, and the command of God became evident—in spite of their dislike.

9:73O Prophet! Strive against the disbelievers and the hypocrites, and be stern with them. Their abode is Hell—what a miserable destination!

9:115God would never lead a people astray, after He had guided them, until He makes clear to them what they should guard against. God has knowledge of all things.

9:120It is not for the inhabitants of Medina and the Desert-Arabs around them to stay behind the Messenger of God, nor to prefer themselves to him. That is because they never suffer any thirst, nor fatigue, nor hunger in the cause of God, nor do they take one step that enrages the disbelievers, nor do they gain anything from an enemy, but it is recorded to their credit as a righteous deed. God does not waste the reward of the righteous.

9:122It is not advisable for the believers to march out altogether. Of every division that marches out, let a group remain behind, to gain understanding of the religion, and to notify their people when they have returned to them, that they may beware.
