صحيح ابن خزيمه
Sahih Ibn Khuzaymah
جماع أبواب ذكر الماء الذي لا ينجس، والذي ينجس إذا خالطته نجاسةChapters on Water that is Pure and Impure
(74) بَابُ الْأَمْرِ بِغَسْلِ الْإِنَاءِ مِنْ وُلُوغِ الْكَلْبِChapter 74: Command to wash the vessel licked by a dog
Hadith Q95
وَالدَّلِيلُ عَلَى أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّمَا أَمَرَ بِغَسْلِ الْإِنَاءِ مِنْ وُلُوغِ الْكَلْبِ تَطْهِيرًا لِلْإِنَاءِ، لَا عَلَى مَا ادَّعَى بَعْضُ أَهْلِ الْعِلْمِ أَنَّ الْأَمْرَ بِغَسْلِهِ أَمْرُ تَعَبُّدٍ، وَأَنَّ الْإِنَاءَ طَاهِرٌ وَالْوُضُوءُ وَالِاغْتِسَالُ بِذَلِكَ الْمَاءِ جَائِزٌ، وَشُرْبُ ذَلِكَ الْمَاءِ طَلْقٌ مُبَاحٌ
And the explanation of the evidence that the command of the Prophet Muhammad (peace be upon him) to wash the vessel in which a dog puts its mouth is for the purification and cleanliness of the vessel, and not, as some scholars have claimed, that the command to wash the vessel is a purely devotional act and that the vessel is pure, and that performing ablution and bathing with that water is permissible, and that drinking that water is absolutely permissible.
