Sayyiduna Abu Dharr (may Allah be pleased with him) said: "That I swear ten times that Ibn Sa'id is the Dajjal is dearer to me than that I swear once that he is not. The reason is that the Messenger of Allah (peace and blessings be upon him) sent me to his mother and said: 'Ask her how long her pregnancy lasted.' I asked her, and she said: 'Twelve months.' Then he (peace and blessings be upon him) said: 'Ask her what his cry was like when he was born.' She said: 'Like the cry of a month-old child.' And the Messenger of Allah (peace and blessings be upon him) himself said to him (Ibn Sa'id): 'I have hidden something for you; tell me what it is.' He said: 'The bone of a whitish-grey sheep.' He wanted to say 'al-dukhan' (smoke), but kept saying: 'al-dukh, al-dukh.' So he (peace and blessings be upon him) said: 'Be gone! You will never get ahead of the decree.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Harith except Abd al-Wahid bin Ziyad."
