It is narrated from Muhammad bin Umar that Sayyiduna Qatadah bin al-Nu'man bin Zayd bin Amr bin Sawad bin Zafar (Zafar's name was Ka'b) bin al-Khazraj bin Amr (who is al-Nabit) bin Malik bin Aws (may Allah be pleased with him), who was the maternal brother of Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him), had the kunya Abu Amr. He was the grandfather of Asim and Ya'qub, the sons of Umar bin Qatadah, and Asim bin Umar was one of the scholars of the sirah and other fields. Qatadah bin al-Nu'man was among the seventy Ansar who attended the Pledge of Aqabah with the Messenger of Allah (peace and blessings be upon him), and he was one of the renowned archers among the Companions of the Messenger of Allah (peace and blessings be upon him). He took part in the Battles of Badr and Uhud. On the day of Uhud his eye (was struck, came out and) fell onto his cheek, so he came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, I have a wife whom I love dearly, and I fear that if she sees this (damaged) eye of mine, she will find it repulsive. So the Messenger of Allah (peace and blessings be upon him) returned it (to its place) with his blessed hand, and it became completely sound, and even in his old age it remained the stronger and sounder of his two eyes. He took part in the Battle of the Trench and in all the battles with the Messenger of Allah (peace and blessings be upon him), and at the Conquest of Makkah the banner of Banu Zafar was with him.

Muhammad bin Umar narrates: Sayyiduna Asim bin Umar bin Qatadah (may Allah be pleased with him) told me that Sayyiduna Qatadah bin al-Nu'man (may Allah be pleased with him) died in the year 23 AH, and he was 65 years old at that time. Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) led his funeral prayer in Madinah, and his maternal brother Sayyiduna Abu Sa'id al-Khudri, Sayyiduna Muhammad bin Maslamah and Sayyiduna al-Harith bin Khazmah (may Allah be pleased with them) went down into his grave.

Mus'ab bin Abdullah al-Zubayri narrates that the name of al-Hadrami, the father of al-Ala, was Abdullah bin Abbad bin Akbar bin Rabi'ah bin Malik bin Uwayf bin Malik bin al-Khazraj. He was an ally of Harb bin Umayyah, and he was called "al-Hadrami" because he came from Hadramawt. The Messenger of Allah (peace and blessings be upon him) had appointed him governor of Bahrain, then Sayyiduna Umar (may Allah be pleased with him) also kept him over Bahrain. He died there, so Sayyiduna Umar (may Allah be pleased with him) appointed Sayyiduna Abu Hurayrah al-Dawsi (may Allah be pleased with him) in his place. He further said that al-Ala bin al-Hadrami died in Bahrain in the year 21 AH.
