Sahih Muslim · Hadith 535

وحدثنا قتيبة بن سعيد، حدثنا ليث، عن ابن الهاد، عن عبد الله بن خباب، عن أبي سعيد الخدري، أن رسول الله صلى الله عليه وسلم ذكر عنده عمه أبو طالب فقال ‏"‏ لعله تنفعه شفاعتي يوم القيامة فيجعل في ضحضاح من نار يبلغ كعبيه يغلي منه دماغه ‏"‏ ‏.‏

Abu Sa'id al-Khudri reported: A mention was made of his uncle Abu Talib before the Messenger of Allah (may peace be upon him) He said: My intercession may benefit him on the Day of Resurrection and he may be placed in the shallow part of the Fire which would reach his ankles and his brain would be boiling.
