"Whoever has a treaty with a people, let him not dissolve it nor reinforce it until its term has passed, or he declares it to them on equal terms." It was recorded by al-Ṭayālisī (1/240/2075): Shuʿbah narrated to us from Abū al-Fiḍḍ al-Shāmī who said: I heard Sulaym ibn ʿĀmir say: "There was a treaty between Muʿāwiyah and the Romans, and he would travel in their lands until the treaty expired, then he would raid them.

This isnād is weak, Simāk — who is Ibn Ḥarb — is truthful, as the ḥāfiẓ said, but his narration from ʿIkrimah specifically is inconsistent, and he changed towards the end of his life, so he might have been prompted
