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