وَعَنْ أُبَيِّ بْنِ كَعْبٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ لِلْوُضُوءِ شَيْطَانًا يُقَالُ لَهُ الْوَلَهَانُ فَاتَّقُوا وَسْوَاسَ الْمَاءِ» . رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ غَرِيبٌ وَلَيْسَ إِسْنَادُهُ بِالْقَوِيِّ عِنْدَ أَهْلِ الْحَدِيثِ لِأَنَّا لَا نَعْلَمُ أَحَدًا أَسْنَدَهُ غَيْرَ خَارِجَةَ وَهُوَ لَيْسَ بِالْقَوِيّ عِنْد أَصْحَابنَا
Ubayy ibn Kaʿb reported that the Prophet said: ‘A devil attends ablution, called al-Walahān, so beware of the whispering caused by water.’
Al-Tirmidhī and Ibn Mājah transmitted it. Al-Tirmidhī called it gharīb and said its chain is not strong according to hadith scholars: they knew of no one who traced it to the Prophet except Khārija, whom their scholars considered weak.
