It is narrated from Imam Muslim bin al-Hajjaj that the kunya of Sayyiduna Ya'la bin Umayyah al-Thaqafi (may Allah be pleased with him) is "Abu al-Murazim", and that he is a Companion of the Messenger.

In this matter Imam Muslim differed with Yahya bin Ma'in, because according to Yahya bin Ma'in "Abu al-Murazim" is the kunya of Sayyiduna Ya'la bin Murrah al-Thaqafi (may Allah be pleased with him). It should be noted that three of the sons of Sayyiduna Ya'la bin Munyah narrated reports from him: Safwan, Uthman and Abd al-Rahman.

It is narrated from Sayyiduna Ya'la bin Umayyah (may Allah be pleased with him) that he said: On the day of the Conquest of Makkah I spoke to the Messenger of Allah (peace and blessings be upon him) about my father Umayyah and said: O Messenger of Allah! Take the pledge of allegiance from my father for emigration (hijrah). The Messenger of Allah (peace and blessings be upon him) said: "I will take his pledge for jihad, for (after the Conquest of Makkah) emigration has now come to an end."

It is narrated from Amr bin Dinar that the first to write dates on letters and official documents was Sayyiduna Ya'la bin Umayyah (may Allah be pleased with him), when he was (governor) in Yemen. For the Prophet (peace and blessings be upon him) arrived in Madinah in the month of Rabi' al-Awwal, and the people reckoned the date from the beginning of the year; however, the people fixed the dating from the time of the arrival of the Prophet (peace and blessings be upon him).

Safwan bin Abdullah narrates from his two paternal uncles, Sayyiduna Ya'la and Sayyiduna Salamah (may Allah be pleased with them both), the sons of Umayyah, that they said: We set out with the Messenger of Allah (peace and blessings be upon him) on the expedition of Tabuk, and with us was a companion of ours. He got into a fight with a man, who bit my companion on the arm. My companion pulled his arm forcefully out of his mouth, and the biter's two front teeth broke and fell out. That man came to the Messenger of Allah (peace and blessings be upon him) seeking blood money (diyah), and he (peace and blessings be upon him) said: "Does one of you go to his brother and bite him the way a stallion bites, and then after that come seeking blood money?! Go, there is no blood money for you." So the Messenger of Allah (peace and blessings be upon him) declared that claim void.

It is narrated from Mus'ab bin Abdullah al-Zubayri that from Banu Salimah, a branch of Banu Jusham bin al-Khazraj, came Sayyiduna Mu'adh, Mu'awwidh and Khallad (may Allah be pleased with them), the sons of Amr bin al-Jamuh bin Zayd bin Haram bin Ka'b. He (Mu'adh) took part in the Battle of Badr and had a share in killing Abu Jahl; in that battle Ikrimah bin Abi Jahl cut off his hand. He lived until the time of Sayyiduna Uthman (may Allah be pleased with him). His mother was Hind bint Amr bin Tha'labah bin Haram, and his paternal uncle was Sayyiduna Jabir bin Abdullah al-Ansari (may Allah be pleased with him), who was present at the Pledge of Aqabah and the Battle of Badr.

It is narrated from Khalifah bin Khayyat that Sayyiduna Mu'adh bin Amr bin al-Jamuh (may Allah be pleased with him) was wounded on the day of Badr and remained continuously bedridden (ill) until the time of Sayyiduna Uthman (may Allah be pleased with him). Then he passed away in Madinah in the year 24 AH; Sayyiduna Uthman bin Affan (may Allah be pleased with him) led his funeral prayer, and he was buried in Jannat al-Baqi'.

It is narrated from Urwah bin al-Zubayr, in his listing of those from Banu Haram bin Ka'b who gave the pledge of allegiance to the Messenger of Allah (peace and blessings be upon him) at the Pledge of Aqabah, that Sayyiduna Mu'adh bin Amr bin al-Jamuh (may Allah be pleased with him) was among them.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "What an excellent man Mu'adh bin Amr bin al-Jamuh is!" This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) that he said: On the day of Badr I was standing in the row. I looked to my right and my left, and found myself between two young boys of the Ansar who were very young in age. I wished that I were between people stronger and sturdier than them. Then one of them nudged me with his elbow and asked: "O uncle! Do you recognise Abu Jahl?" I said: Yes, but what do you want with him, my nephew? He said: I have been told that he insults the Messenger of Allah (peace and blessings be upon him). By the One in whose Hand is my soul! If I see him, my body will not part from his body until whichever of us is destined to die first dies. I was greatly astonished at what he said. Then the other boy nudged me in the same way and said the same thing to me. Only a short while had passed when I saw Abu Jahl moving about among the people. I said to the two of them: Look! This is the man you were asking me about. On hearing this, both of them rushed at him with their swords drawn and struck him until they killed him. Then they came to the Messenger of Allah (peace and blessings be upon him) and informed him of what had happened. He (peace and blessings be upon him) asked: "Which of you killed him?" Each of them claimed: I killed him. He (peace and blessings be upon him) asked: "Have you wiped your swords clean?" They said: No. He (peace and blessings be upon him) examined both swords and said: "Both of you killed him." Then he (peace and blessings be upon him) awarded Abu Jahl's battle gear (salab) to Sayyiduna Mu'adh bin Amr bin al-Jamuh (may Allah be pleased with him). The two of them were Mu'adh bin Afra' and Mu'adh bin Amr bin al-Jamuh (may Allah be pleased with them both).
