Virtues of As'ad bin Zurarah (may Allah be pleased with him): As'ad bin Zurarah was the first to establish the Friday prayer in Madinah

It is narrated from Abd al-Rahman bin Abi al-Rijal that As'ad bin Zurarah (may Allah be pleased with him) died in the month of Shawwal, at the beginning of the ninth month after the Hijrah. At that time the mosque of the Messenger of Allah (peace and blessings be upon him) was being built, and this was before the Battle of Badr. The Banu al-Najjar came to the Messenger of Allah (peace and blessings be upon him) and said: "Our Naqib (chief) has passed away, so appoint a Naqib for us." The Messenger of Allah (peace and blessings be upon him) said: "I am your Naqib."

It is narrated from Abdullah bin Abi Bakr bin Amr bin Hazm that the first person to be buried in Jannat al-Baqi' was As'ad bin Zurarah (may Allah be pleased with him).

Abd al-Rahman bin Ka'b bin Malik narrates concerning his father; he said: I used to lead my father after he had lost his sight. Whenever he heard the adhan for Jumu'ah, he would say: "May Allah's mercy be upon As'ad bin Zurarah." After some time I thought I would ask my father why, on hearing the adhan, he prayed for mercy for As'ad bin Zurarah. I said: "O my father, whenever you hear the adhan for Jumu'ah, this prayer of yours for Abu Umamah (As'ad) strikes me; what is the reason for it?" He said: "O my dear son, he was the first to establish the Jumu'ah prayer for us in Madinah, at a level spot in the Harrah of Banu Bayadah called Naqi' al-Khadimat." I asked: "How many of you were there that day?" He said: "Forty men."

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) cauterized As'ad bin Zurarah (may Allah be pleased with him) because of "shawkah" (a kind of epidemic affliction).
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
