I would like an account of the character of Abu Dharr al-Ghifari.

Abu Dharr al-Ghifari, Jundub ibn Junadah, was among the earliest converts to Islam, and the fourth of four individuals to embrace it. He accepted Islam in Mecca, and the Prophet, peace and blessings be upon him, ordered him to return to his people. However, he openly proclaimed his faith among the polytheists, who then beat him until Al-Abbas rescued him. He returned to his people and did not emigrate until after the Battles of Badr and Uhud. He was a subject of the Prophet's special attention and was characterized by asceticism. The Prophet said about him: "No one more truthful in speech has been carried by the earth nor shaded by the sky than Abu Dharr." He also said about him: "May Allah have mercy on Abu Dharr; he lives alone, dies alone, and will be resurrected alone." He passed away in the year 31 AH in Al-Rabadhah, and Ibn Mas'ud led his funeral prayer.
