وَفِي شَرْحِ السُّنَّةِ عَنْهُ عَنْ مَيْمُونَةَ بِلَفْظِ المصابيح
Ibn ‘Abbas said that a wife of the Prophet washed in a bowl, and when God’s messenger wanted to perform ablution from it she said, “I was defiled, messenger of God.” He replied, “Water does not become defiled.” Tirmidhi, Abu Dawud, and Ibn Majah transmitted it, and Darimi has something similar. In Sharh as-sunna it is given from him from Maimuna with the wording in al-Masabih.
