Concerning eating and drinking of one who is sexually impure
Sunan Ibn Majah
حَدَّثَنَا مُحَمَّدُ بْنُ عُمَرَ بْنِ هَيَّاجٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ صُبَيْحٍ، حَدَّثَنَا أَبُو أُوَيْسٍ، عَنْ شُرَحْبِيلَ بْنِ سَعْدٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ سُئِلَ النَّبِيُّ ـ صلى الله عليه وسلم ـ عَنِ الْجُنُبِ هَلْ يَنَامُ أَوْ يَأْكُلُ أَوْ يَشْرَبُ قَالَ " نَعَمْ إِذَا تَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ " .
It was narrated that Jabir bin 'Abdullah said: "The Prophet was asked about whether a person who is sexually impure can sleep, or eat, or drink. He said: 'yes, if he does ablution as for the prayer.'"
