The Jews of Madinah had already become guilty by rejecting the prophethood of the Prophet Muhammad. The gravity of their guilt was further increased by their breaking of the pledge. After the emigration to Madinah, there had been a written agreement between the Prophet and the Jews of Madinah that both the sides would be neutral in matters relating to each other. But the Jews started conspiring against him, secretly joining hands and collaborating with his enemies. This was breach of trust in addition to the rejection of truth. Punishment awaits such people in the Hereafter. And in this world they will be discouraged from creating further mischief. If the Muslims have a treaty with a community, but they want to cancel it for fear of its being breached by that community, it is necessary that they should first inform those co-signatories, so that it is known in advance that the treaty no longer exists between them. The position is different when there is not merely the fear of a beach of trust but there has been a clear contravention of the treaty. In such a case it is permissable to start retaliatory action without informing the other party. The campaign of Makkah is an example of this type. The Quraysh had unilaterally contravened the Hudaibiyah treaty by joining the Banu Bakr’s aggression against an ally of the Prophet Muhammad, namely, the Banu Khuza‘a. So the Prophet quietly proceeded against the Quraysh without giving them advance information.
