[Machine] The Messenger of Allah, ﷺ , said: "If one of you is sleeping and then wakes up and wants to perform ablution, do not put his hand in the vessel until he pours water on his hand, for he does not know where his hand has spent the night."
قَالَ رَسُولُ اللهِ ﷺ إِذَا كَانَ أَحَدُكُمْ نَائِمًا ثُمَّ اسْتَيْقَظَ وَأَرَادَ الْوُضُوءَ فَلَا يَضَعْ يَدَهُ فِي الْإِنَاءِ حَتَّى يَصُبَّ عَلَى يَدِهِ فَإِنَّهُ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ
