باب مَا يَقُولُ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ ‏
Sahih Muslim 476 d

This hadith with the same chain of transmitters has been narrated by Shu'ba, and in the narration of Mu'adh the words are:

" just as the white garment is cleansed from filth," and in the narration of Yazid:" from dirt".
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي ح، قَالَ وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، كِلاَهُمَا عَنْ شُعْبَةَ، بِهَذَا الإِسْنَادِ فِي رِوَايَةِ مُعَاذٍ ‏"‏ كَمَا يُنَقَّى الثَّوْبُ الأَبْيَضُ مِنَ الدَّرَنِ ‏"‏ ‏.‏ وَفِي رِوَايَةِ يَزِيدَ ‏"‏ مِنَ الدَّنَسِ ‏"‏ ‏.‏
