Allah took covenants from the children of Adam, the prophets, the Children of Israel, the People of the Book and the believers: these verses speak of them and command keeping one’s pledges, praising those who honour them and blaming those who break them. They also address treaties with enemies: honouring them until their term as long as the other side does, and openly declaring their termination.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
They wish you would disbelieve as they disbelieved so you would be alike. So do not take from among them allies until they emigrate for the cause of Allāh. But if they turn away [i.e., refuse], then seize them and kill them [for their betrayal] wherever you find them and take not from among them any ally or helper,
And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment [diyah] presented to his [i.e., the deceased's] family [is required], unless they give [up their right as] charity. But if he [i.e., the deceased] was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allāh. And Allāh is ever Knowing and Wise.
Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allāh and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no support of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allāh is Seeing of what you do.
