Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them) narrates: A Muhajir and an Ansari beat each other. The Ansari said: O Ansar (come to my help), and the Muhajir said: O Muhajirin (come to my help). The Prophet (peace and blessings of Allah be upon him) heard this. He said: What is this matter of calling out like the days of ignorance? The people said: O Messenger of Allah (peace and blessings of Allah be upon him)! A Muhajir has struck an Ansari. The Prophet (peace and blessings of Allah be upon him) said: Leave this thing, for it is foul. Upon this, Abdullah bin Ubayy said: They have done this; when we return to Madinah, the honorable among us will surely expel the lowly ones from there. Then Sayyiduna Umar (may Allah be pleased with him) said: O Messenger of Allah (peace and blessings of Allah be upon him)! Allow me to strike the neck of this hypocrite. The Prophet (peace and blessings of Allah be upon him) said: Leave him, otherwise people will say that Muhammad kills his companions.

(Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet (peace and blessings of Allah be upon him), "This thing is foul," by this he meant that there will be no retaliation (qisas) in it. Similarly, when people say: "This thing is blameworthy," or similar words, this is what is meant.
