Mukhtasar Bukhari

Narrated from Sayyiduna Abbas bin Abdul Muttalib (may Allah be pleased with him) that he said to the Prophet (peace and blessings of Allah be upon him): "O Messenger of Allah! What help did you give to your uncle? He used to protect you and get angry for your sake." The Prophet (peace and blessings of Allah be upon him) said: "He is in fire up to his ankles, and if I had not interceded for him, he would have been in the lowest depth of Hell."

It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that he heard from the Noble Prophet, peace and blessings be upon him, when the mention of his (the Prophet's) uncle (Abu Talib) came up, the Prophet, peace and blessings be upon him, said: "On the Day of Resurrection, perhaps my intercession will benefit him so much that he will be placed in shallow fire reaching up to his ankles, from which his brain will boil."
