Volume: 004 / Book Number: 056 / Hadith Number: 724
Narrated Ibn Abbas:
When the news of the advent of the Prophet reached Abu Dhar, he said to his brother, "Ride to this valley and bring me the news of this man (i.e. the Prophet ) who claims to be a Prophet receiving information from the Heaven. Listen to him and then come to me." His brother set out till he met the Prophet and listened to his speech and returned to Abu Dhar and said to him, "I have seen him exhorting people to virtues and his speech was not like poetry." Abu Dhar said, "You have not satisfied me as to what I wanted." So, he took his journey-food and a water-skin full of water and set out till he reached Mecca, where he went to the Mosque looking for the Prophet , whom he did not know, and he would not like to ask someone about him. So, a portion of the night had passed when 'Ali saw him and realized that he was a stranger. Abu Dhar followed him (to his house), but neither of them asked the other about anything till it was morning, when he carried his water-skin and food and went to the Mosque. He spent that day without being observed by the Prophet till it was night, when he returned to his sleeping place. 'Ali again passed by him and said, "Hasn't the man (i.e. Abu Dhar) recognized his dwelling place yet?" So, 'Ali let him get up and took him (to his house), but neither of them asked the other about anything, till it was the third day when 'Ali had the same experience with him and Abu Dhar again stayed with him. 'Ali then asked, "Won't you tell me what has brought you here?" He replied, "If you give me a promise and a convention that you will guide me, then I will tell you." When 'Ali did, Abu Dhar informed him (of his purpose). 'Ali said, "It is the Truth, and he (i.e. Muhammad) is the Apostle of Allah. So when the morning comes, follow me, and if I should perceive any danger threatening you, I will give you a hint by pretending to go to the watercloset. But if I carried on walking, follow me till you enter the place that I will enter." Abu Dhur agreed and followed 'Ali till he entered the place of the Prophet and Abu Dhur entered with him. He then listened to the speech of the Prophet and embraced Islam on that very spot. The Prophet said to him, "Go back to your people and inform them (of this religion) till you receive my (further) orders." Abu Dhur said, "By Him in Whose Hands my life is! I will proclaim my conversion to Islam publicly amongst them (i.e. infidels)." He went out till he reached the Mosque and announced as loudly as possible, "I testify that None has the right to be worshipped but Allah and that Muhammad is the Apostle of Allah." The people then got up and beat him till they knocked him down. Al-Abbas came and threw himself over him (to protect him) saying, Woe to you! Don't you know that he is from Ghifar and there is the route (road) to your merchants towards Sham (i.e. through the place where this tribe dwells)?" Thus he saved him from them. Abu Dhar did the same on the next day and the people beat him again and Al-'Abbas drew himself over him (to save him as before).
