The Prophet ﷺ said, "Perform ablution from what fire has changed."Ibn Abbas asked, "Should I perform ablution from hot water?"He replied, "Nephew, when you hear a hadith from the Messenger of Allah ﷺ, do not strike comparisons against it."
حدثنا محمد بن الصباح حدثنا سفيان بن عيينة عن محمد بن عمرو بن علقمة عن أبي سلمة بن عبد الرحمن
أن النبي ﷺ قال توضئوا مما غيرت النار فقال ابن عباس أتوضأ من الحميم فقال له يا ابن أخي إذا سمعت عن رسول الله ﷺ حديثا فلا تضرب له الأمثال
[Hasan] Mentioned previously, no. 22. Tirmidhi recorded it, no. 79, from the narration of Sufyan through the same chain. Ahmad recorded it in 1/366 with a sahih chain, from Ibn Abbas, that in this debate he said to Abu Hurairah , "I do not care what I performed wudu over. I testify that I saw the Messenger of Allah eat a shoulder of meat, then get up for prayer without performing wudu." So each side has its own proof, and each is excused.
