Arabic (Original)
حَدَّثَنَا يَزِيدُ حَدَّثَنَا مُحَمَّدٌ يَعْنِي ابْنَ إِسْحَاقَ عَنْ مُوسَى بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ وَعَنِ الزُّهْرِيِّ وَغَيْرِهِ قَالُوا قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اسْتَيْقَظَ أَحَدُكُمْ فَلَا يَضَعَنَّ يَدَهُ فِي الْغِسْلِ حَتَّى يَغْسِلَهَا فَإِنَّهُ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ.
English Translation
Yazid told us: Muhammad - that is, Ibn Ishaq - told us, from Musa b. Yasar, from Abu Hurayrah, and from al-Zuhri and others, who said: The Messenger of Allah, peace and blessings be upon him, said: "When one of you wakes up, let him not put his hand into the water vessel until he washes it, for he does not know where his hand spent the night."
