The holy phrase...
The holy phrase: “(This is a declaration of) immunity from Allah ” indicates that this acquittal is from the side of Allah. And the, phrase: “and His Messenger ” , mentioned immediately after it, means that the strings of promises and treaties were cut off, respites were ended, and agreements were cancelled. The addressee ‘you’ in the sentence: “towards those of the polytheists with whom you made covenant ” is both the Messenger of Allah (S) and the Muslims.
Thus, it means that they should declare immunity unto the polytheists between whom and them there was an agreement, because Allah (s.w.t.) and His Messenger (S) are quit of them. The objective meaning here is that Allah (s.w.t.) and His Messenger (S) are quit of giving a promise to them and, after that, fulfilling it, because the polytheists who made covenants with them broke their promises.
If someone asks how it is permissible for the Prophet (S) to break his promise, the answer is that it is permissible for the Prophet (S) to break his promise by one of the following ways: The fulfilment of the promise was conditioned that there would not come any other command from Allah, the Exalted, upon it, and since there came down a revelation instructing that there would remain no covenant thereafter, the Messenger of Allah (S) broke the covenant.
Since treachery and perjury was made manifest from the side of idolaters, Allah, the Exalted, instructed His Prophet (S) to break their covenant, too. That covenant was not a permanent (and an absolute) treaty, but it was bound over a definite point of time and for a certain length of time, so that when its term was ended that covenant would be broken, either.
It has also been pointed out in some traditions that the Messenger of Allah (S) had conditioned the above mentioned matters with them in the treaty. It has also been narrated that the idolaters broke their promise or decided to break it. Then, Allah, the Glorified, commanded His Prophet to break their covenant, too Next to that, through the following verse, Allah, the Glorified, addressing the idolaters, says: “So go about in the earth…”.
Explanations 1- Fulfilment the promise, yes; but surrending to plots, never.
