Sahih Muslim, 1382 b
sahih

This hadith has been narrated by Yabya b. Sa'id with the same chain of transmitters (and the words are):

" Just as a furance removes impurity," but no mention is made of iron.

وَحَدَّثَنَا عَمْرٌو النَّاقِدُ، وَابْنُ أَبِي عُمَرَ، قَالاَ حَدَّثَنَا سُفْيَانُ، ح وَحَدَّثَنَا ابْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، جَمِيعًا عَنْ يَحْيَى بْنِ سَعِيدٍ، بِهَذَا الإِسْنَادِ وَقَالاَ ‏

‏ كَمَا يَنْفِي الْكِيرُ الْخَبَثَ

‏ ‏.‏ لَمْ يَذْكُرَا الْحَدِيدَ .
