Zayd ibn Arqam

Zayd ibn Arqam ibn Zayd al-Ansari al-Khazraji (died approximately 65 AH) was a companion of the Prophet ﷺ. He participated in many battles with the Prophet ﷺ including Khandaq. He is perhaps best known as the primary narrator of the Hadith al-Thaqalayn — the Prophet's statement at Ghadir Khumm: 'I am leaving among you two weighty things: the Book of Allah and my Ahl al-Bayt.' This hadith is in Sahih Muslim and is considered authentic by all Muslims. He narrated many other hadiths and lived in Kufa.
