3518. Narrated Jābir رضي الله عنه: We were in the company of the Prophet ﷺ in a Ghazwa. A large number of Muhājrun (emigrants) joined him, and among the Muhājrun there was a person who used to play jokes (or play with spears); so he (jokingly) stroked an Anṣārī man on the hip. The Anṣārī got so angry that both of them called their people. The Anṣārī said, "Help, O Anṣārī!" And the Muhājir said, "Help, O Muhājir!" The Prophet ﷺ came out and said, "What is wrong with the people (as they are calling) this call of the (Pre-Islāmic) Period of Ignorance?" Then he said, "What is the matter with them?" He was told about the stroke of the Muhājir to the Anṣārī. The Prophet ﷺ said, "Stop this for it is an evil call." 'Abdullāh bin Ubaī bin Salūl (a hypocrite) said, "The Muhājrun have called and (gathered against us); so when we return to Al-Madīna, surely, the more honourable people will expel therefrom the meaner." Upon that 'Umar said, "O Allāh's Prophet! Shall we not kill this Khabīth (evil person i.e., Abdullāh bin Ubaī bin Salūl)?" The Prophet ﷺ said, "(No), lest the people should say that Muḥammad used to kill his companions."
