Narrated Abdullah ibn Abbas: The Prophet ﷺ forbade that the food of two people who were rivalling on another should be eaten Abu Dawud said: Most of those who narrated it from Jarir did not mention the name of Ibn Abbas. Harun al-Nahwi mentioned Ibn 'Abbas in it, and Hammad bin Zaid did not mention Ibn 'Abbas.
The Prophet's prohibition against eating the food of two rivals also serves as a reminder for us to be mindful of our actions when it comes to taking part in competitions or disputes between others. We should strive to remain impartial and unbiased so that we do not inadvertently contribute towards furthering any animosity or ill-will between those involved.
