Sunan Ibn Majah, Book 9, Hadith 2084 (In-Book) ⓘ
It was narrated from Abu Hurairah that: the Prophet said: "The child is for the bed (i.e., belongs to the husband) and the fornicator gets nothing!'
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ " الْوَلَدُ لِلْفِرَاشِ . وَلِلْعَاهِرِ الْحَجَرُ " .
