Narrated by ʿAmr ibn Maymun: ʿUmar رضي الله عنه [after he was stabbed], instructed [his would-be-successor] saying:
"I urge him [i.e. the new Caliph] to take care of those non-Muslims who are under the protection of Allāh and His Messenger in that he should observe the convention agreed upon with them, and fight on their behalf (to secure their safety) and he should not over-tax them beyond their capability."
[Ṣaḥīḥ al-Bukhārī 3052]
