It was said to the Prophet (ﷺ) "Would that you see `Abdullah bin Ubai." So, the Prophet (ﷺ) went to him,
riding a donkey, and the Muslims accompanied him, walking on salty barren land. When the Prophet (ﷺ)
reached `Abdullah bin Ubai, the latter said, "Keep away from me! By Allah, the bad smell of your
donkey has harmed me." On that an Ansari man said (to `Abdullah), "By Allah! The smell of the
donkey of Allah's Messenger (ﷺ) is better than your smell." On that a man from `Abdullah's tribe got angry
for `Abdullah's sake, and the two men abused each other which caused the friends of the two men to
get angry, and the two groups started fighting with sticks, shoes and hands. We were informed that the
following Divine Verse was revealed (in this concern):-- "And if two groups of Believers fall to
fighting then, make peace between them." (49.9) - Hadith Al Bukhari 2691 (islam)
