It is narrated from Muhammad bin Wasi'; he said: I went to Bilal bin Abi Burdah and said to him: "O Bilal! Indeed, your father narrated to me, through your grandfather, this hadith of the Messenger of Allah (peace and blessings be upon him), that he (peace and blessings be upon him) said: 'Indeed, in Hell there is a valley. In that valley there is a well called Habhab, and it is a right upon Allah Almighty that He will make every tyrant dwell in it.' So beware, O Bilal, of becoming one of them." Azhar bin Sinan is alone in narrating this hadith from Muhammad bin Wasi'; we have written it with a high chain (with few intermediaries) only through this route.
