عَنْ أَنَسٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا دَخَلَ الْخَلَاءَ نَزَعَ خَاتَمَهُ. رَوَاهُ أَبُو دَاوُدَ وَالنَّسَائِيُّ وَالتِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ وَقَالَ أَبُو دَاوُدَ: هَذَا حَدِيثٌ مُنْكَرٌ. وَفِي رِوَايَتِهِ وَضَعَ بَدَلَ نزع

Abu Musa said

One day when I was with the Prophet he wanted to pass water, so he went to some soft ground at the foot of a wall and did it, after which he said, "When any of you wishes to pass water, he should look for [a place like this] to do it in.” Abu Dawud transmitted it.
