سُنَنُ ابْنِ مَاجَهْ
Sunan Ibn Majah 393
The Book of Purification and its Sunnah
When a man wakes up from sleep: should he put his hand in the vessel before washing it?
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، حَدَّثَنِي الزُّهْرِيُّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ أَنَّهُمَا حَدَّثَاهُ أَنَّ أَبَا هُرَيْرَةَ كَانَ يَقُولُ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنَ اللَّيْلِ فَلاَ يُدْخِلْ يَدَهُ فِي الإِنَاءِ حَتَّى يُفْرِغَ عَلَيْهَا مَرَّتَيْنِ أَوْ ثَلاَثًا فَإِنَّ أَحَدَكُمْ لاَ يَدْرِي فِيمَ بَاتَتْ يَدُهُ .
Sa'eed bin Musayyab and Abu Salamah bin 'Abdur-Rahman narrated that : Abu Hurairah used to say: "The Messenger of Allah said: 'When anyone of you wakes up from sleep, he should not put his hand into the vessel until he has poured water on it two or three times, for none of you knows where his hand spent the night,'"
