Then he extended the same principle to all other matters, saying, ʺBehave not treacherously, even towards those who are treacherous to you.ʺ And he impressed this principle so deeply on their minds that it was observed most strictly, both in spirit and in letter.ʺ
There is, however, an exception to the above principle.
When the enemy has actually violated the treaty openly in such a flagrant manner that the treaty is understood to have been abrogated and cancelled, in such circumstances, there is no need to throw their treaty openly before them, because the other party, by violating its terms, has clearly shown that the treaty is no longer binding unless it is renegotiated.
It may, however, be pointed out that the violation of the treaty on the part of the enemy must be open and glaring, about which there should be no doubt in the minds of the other party.
Muhammed peace be and blessings upon him observed this principle very strictly in all his agreements. In the case of the Jews of Medinah, he went himself or sent someone to remind them of their mutual obligations and to confirm their position regarding the agreement. He did this every time they violated the terms of their agreement.
When the other party showed openly by their action that they did not care for him or for his agreements, only then was action taken against them.
