It is narrated from Imam al-Hasan al-Basri (may Allah have mercy on him) that a man came and stayed as a guest with Sayyiduna Ali (may Allah be pleased with him), and he hosted him. Then the man said: "I want to bring a case (a claim)." Sayyiduna Ali (may Allah be pleased with him) said to him: "Move (from here) to some other place, for the Prophet (peace and blessings be upon him) forbade us 'to host a party to a dispute unless his opposing party (the defendant) is with him.'"
This narration is reported in Musnad Ishaq bin Rahwayh (hadith: 2181).

Nu'aym (may Allah have mercy on him) states: I was present at the court session of Sayyiduna Abu Hurayrah (may Allah be pleased with him). Meanwhile al-Harith bin al-Hakam came and sat on the cushion of Sayyiduna Abu Hurayrah (may Allah be pleased with him) on which he was reclining. Sayyiduna Abu Hurayrah (may Allah be pleased with him) assumed that he had come for some need other than a judgement. Then another man came and sat in front of Sayyiduna Abu Hurayrah (may Allah be pleased with him). He (may Allah be pleased with him) asked him: "What is your matter?" He said: "Al-Harith has demanded his right against me." So Sayyiduna Abu Hurayrah (may Allah be pleased with him) said (to al-Harith): "Get up and sit beside your opponent, for this is the Sunnah (blessed way) of Sayyiduna Abu al-Qasim (peace and blessings be upon him)."
This narration is from Musnad al-Harith; Imam al-Harith bin Abi Usamah (may Allah have mercy on him) recorded it in his Musnad.

It is narrated from al-Muttalib (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever backs a quarrelling party (unjustly) while being ignorant of the reality of the matter remains continually under the wrath of Allah (Allah Almighty's severe displeasure) until he withdraws from that (support)."
Imam Abu Bakr bin Abi Shaybah (may Allah have mercy on him) narrated this hadith in his book al-Musannaf.
