Abbas bin Abdul-Muttalib reported,

Someone asked, "Messenger of Allah, have you been able to benefit Abu Talib in any way? He used to protect you and grow angry on your behalf."He replied, "Yes, he is in a shallow pool of fire. Were it not for me, he would be in the lowest depths of the Fire."In another wording, "Yes, I found him plunged in the depths of the Fire, and I brought him out to a shallow pool."

عن عباس بن عبد المطلب قال

يا رسول الله هل نفعت أبا طالب بشيء؟ فإنه كان يحوطك ويغضب لك، قال: نعم، هو في ضحضاح من نار، لولا أنا لكان في الدرك الأسفل من النار. وفي لفظ: نعم، وجدته في غمرات من النار فأخرجته إلى ضحضاح.
