[Machine] The Messenger of Allah ﷺ said, "When one of you wakes up, he should not put his hand in the water for washing until he washes it, as he does not know where his hand has spent the night."
قَالَ رَسُولُ اللهِ ﷺ إِذَا اسْتَيْقَظَ أَحَدُكُمْ فَلَا يَضَعَنَّ يَدَهُ فِي الْغِسْلِ حَتَّى يَغْسِلَهَا فَإِنَّهُ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ
