Habib bin Abi Mulaykah (may Allah have mercy on him) narrates: I was sitting beside Sayyiduna Ibn Umar (may Allah be pleased with them both) when a man came to him and said: "O Abu Abd al-Rahman! Tell me about Uthman: did he take part in Badr?" He said: "No." He said: "Did he take part in the Pledge of Ridwan?" He said: "No." He said: "Was he among those who turned their backs on the day the two armies met?" He said: "Yes." (Hearing this) the man turned and walked away. Then (another) man said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): "This man will now go and tell people that you have spoken disrespectfully of Sayyiduna Uthman (may Allah be pleased with him)." He said: "Did I do that?" He said: "That is what he thinks." So he said: "Bring that man back to me." So the people called him back. He asked: "Do you know what I said to you?" The man said: "I asked you whether Uthman took part in Badr, and you said: No. And I asked you whether he took part in the Pledge of Ridwan, and you said: No. And I asked you whether he was among those who turned their backs on the day the two armies met, and you said: Yes." Then Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "The Messenger of Allah (peace and blessings be upon him) said on the day of Badr: 'Uthman has been held back by a task for Allah and His Messenger.' So the Messenger of Allah (peace and blessings be upon him) allotted him a share (of the spoils), and he did not allot a share to anyone else who was absent. And at the time of the Pledge of Ridwan, the Messenger of Allah (peace and blessings be upon him) had sent Sayyiduna Uthman (may Allah be pleased with him) to Makkah to seek permission from the people of Makkah concerning the sacrificial animals and entering Makkah. Then he (peace and blessings be upon him) took the Pledge of Ridwan while he (peace and blessings be upon him) intended to enter Makkah, and he (peace and blessings be upon him) said: 'Uthman has gone on a task for Allah and His Messenger, so I pledge allegiance to Allah on his behalf.' Then he (peace and blessings be upon him) struck one of his hands upon the other." And (as for turning back), Allah Almighty has said: "Indeed, those of you who turned back on the day the two armies met, it was only Satan who caused them to slip because of some of what they had earned. And Allah has certainly pardoned them." So go, Allah Almighty has already pardoned them; now go and do your utmost against me.
Imam al-Tabarani (may Allah have mercy on him) said: "None of those who narrated this hadith with this chain placed Hani bin Qays between Kulayb bin Wa'il and Habib bin Abi Mulaykah except Abd al-Wahid bin Ziyad. Za'idah and a group narrated it from Kulayb bin Wa'il, from Habib bin Abi Mulaykah, from Ibn Umar (may Allah be pleased with them both). Habib bin Abi Mulaykah's kunyah is Abu Thawr al-Huddani; (Huddan) is a branch of the tribe of Murad."
