Imam al-Sha'bi (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) said: "I arranged the marriages of al-Miqdad and Zayd so that whoever among you is best in character would be the highest in rank with Allah."
This report is munqati' (has a broken chain), and the report before it is sufficient.
(b) Sayyiduna al-Miqdad (may Allah be pleased with him) is the son of Amr bin Tha'labah bin Malik; he was an ally of al-Aswad, a man from Banu Zuhrah, and so he was attributed to him, though he was not of their lineage; and Sayyidah Duba'ah bint al-Zubayr bin Abd al-Muttalib bin Hashim (may Allah be pleased with her) was married to him.
