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
Translation
Ruwaifi' b. Thabit told that God’s messenger said to him, “You may live for a long time after I am gone, Ruwaifi', so tell people that if anyone ties his beard, or wears round his neck a string to ward off the evil eye, or cleanses himself with animal dung or bone, Muhammad has nothing to do with him. Abu Dawud transmitted it.
