[Machine] The Messenger of Allah ﷺ said: "When one of you wakes up from his sleep, let him wash his hands before placing them in his ablution, for one of you does not know where his hand has spent the night."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ نَوْمِهِ فَلْيَغْسِلْ يَدَهُ قَبْلَ أَنْ يُدْخِلَهَا فِي وَضُوئِهِ فَإِنَّ أَحَدَكُمْ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ
