Bulugh al-Maram #88
The Book of Purification
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَقَالَ اَلْبُخَارِيُّ: هُوَ أَصَحُّ شَيْءٍ فِي هَذَا اَلْبَابِ.
and Al-Bukhari said, “It is the most authentic in this chapter”.
