It is narrated from Miqsam that Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) came to Sayyiduna Mu'awiyah (may Allah be pleased with him) and mentioned a need of his. He said: "Are you not the companion of Uthman (may Allah be pleased with him)?" He replied: "Know that the Messenger of Allah (peace and blessings be upon him) informed us beforehand that after him we would face favouritism and preference of others over us (and denial of our rights)." He asked: "Then what did he (peace and blessings be upon him) command you?" He said: "He (peace and blessings be upon him) commanded us to be patient until we meet him at the Pond (al-Kawthar)." Sayyiduna Mu'awiyah (may Allah be pleased with him) said: "Then be patient." At this, Sayyiduna Abu Ayyub (may Allah be pleased with him) became angry and swore that he would never speak to him again. Then Sayyiduna Abu Ayyub (may Allah be pleased with him) came to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) and told him the whole story. So Ibn Abbas vacated his house for him just as Sayyiduna Abu Ayyub had vacated his house for the Messenger of Allah (peace and blessings be upon him). He asked: "What do you want?" He said: "Four slaves to work at my place." Ibn Abbas (may Allah be pleased with them both) said: "I have twenty slaves for you." This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
