It is narrated from Ibn Ishaq, concerning those who took part in the Pledge of Aqabah, that among them was Mu'adh bin Jabal bin Amr bin Aws bin A'idh bin Adi bin Ka'b bin Ghanm bin Sa'd bin Ali bin Asad bin Saridah bin Tazid bin Jusham. He belonged to Banu Salimah. He took part in the Battle of Badr and in all the battles alongside the Messenger of Allah (peace and blessings be upon him). He passed away in the plague of Amwas in Syria during the caliphate of Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). Banu Salimah attributed him to themselves because he had established brotherhood with one of their men.
