When anyone amongst you wakes up from sleep, he must not put his hand in the utensil till he has washed it three times, for he does not know where his hand was during the night.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ نَوْمِهِ فَلاَ يَغْمِسْ يَدَهُ فِي الإِنَاءِ حَتَّى يَغْسِلَهَا ثَلاَثًا فَإِنَّهُ لاَ يَدْرِي أَيْنَ بَاتَتْ يَدُهُ  

This hadith is transmitted from Abu Huraira by another chain of transmitters.  

قَالَ رَسُولُ اللَّهِ ﷺ وَفِي حَدِيثِ وَكِيعٍ قَالَ يَرْفَعُهُ بِمِثْلِهِ  

Zahri and Ibn Musayyab have both transmitted a hadith like this from Abu Huraira who narrated it from the Apostle ﷺ.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ  

The Apostle of Allah ﷺ said: When anyone amongst you wakes up from sleep, he should wash his hands three times before putting it in the utensil, for he does not know where his hand was during the night.  

أَنَّهُ أَخْبَرَهُ أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا اسْتَيْقَظَ أَحَدُكُمْ فَلْيُفْرِغْ عَلَى يَدِهِ ثَلاَثَ مَرَّاتٍ قَبْلَ أَنْ يُدْخِلَ يَدَهُ فِي إِنَائِهِ فَإِنَّهُ لاَ يَدْرِي فِيمَ بَاتَتْ يَدُهُ  

This hadith has been transmitted through other chains of transmitters on the authority of Abu Huraira in which it is reported that the Messenger of Allah ﷺ made a mention of washing the hand, and did not instruct to wash it three times. But the hadith narrated from Jabir and Ibn Musayyab. Abu Salama, and Abdullah b. Shaqiq, Abu Salih, Abla Razin, there is a mention of" three times".  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ كُلُّهُمْ يَقُولُ حَتَّى يَغْسِلَهَا وَلَمْ يَقُلْ وَاحِدٌ مِنْهُمْ ثَلاَثًا إِلاَّ مَا قَدَّمْنَا مِنْ رِوَايَةِ جَابِرٍ وَابْنِ الْمُسَيَّبِ وَأَبِي سَلَمَةَ وَعَبْدِ اللَّهِ بْنِ شَقِيقٍ وَأَبِي صَالِحٍ وَأَبِي رَزِينٍ فَإِنَّ فِي حَدِيثِهِمْ ذِكْرَ الثَّلاَثِ
