It is unlawful for the wife to refuse to come to her husband's bed
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا مَرْوَانُ، عَنْ يَزِيدَ، - يَعْنِي ابْنَ كَيْسَانَ - عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " وَالَّذِي نَفْسِي بِيَدِهِ مَا مِنْ رَجُلٍ يَدْعُو امْرَأَتَهُ إِلَى فِرَاشِهَا فَتَأْبَى عَلَيْهِ إِلاَّ كَانَ الَّذِي فِي السَّمَاءِ سَاخِطًا عَلَيْهَا حَتَّى يَرْضَى عَنْهَا " .
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying: By Him in Whose Hand is my life, when a man calls his wife to his bed, and she does not respond, the One Who is in the heaven is displeased with her until he (her husband) is pleased with her.
