Salamah ibn al-Muhabbiq reported: A man had intercourse with the servant girl of his wife, so the matter was referred to the Prophet, peace and blessings be upon him. The Prophet said, “If she had done so willingly, then she belongs to him and he must pay the likes of her price. If he had forced her, then she is free and he must pay the likes of her price.”

Grade: Hasan (fair) according to Ibn al-Qayyim
Ibn al-Qayyim said, “If he had forced her, this is a type of abuse as compulsion into sexual intercourse is abuse. Indeed, such intercourse is carried out in the manner of a criminal offense, so for this reason, he is not absolved from a fine or legal punishment.”

عَنْ سَلَمَةَ بْنِ الْمُحَبِّق أَنَّ رَجُلًا وَقَعَ عَلَى جَارِيَةِ امْرَأَتِهِ فَرُفِعَ ذَاكَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ إِنْ كَانَتْ طَاوَعَتْهُ فَهِيَ لَهُ وَعَلَيْهِ مِثْلُهَا لَهَا وَإِنْ كَانَ اسْتَكْرَهَهَا فَهِيَ حُرَّةٌ وَعَلَيْهِ مِثْلُهَا لَهَا

قال ابن القيم وَأَمَّا إذَا اسْتَكْرَهَهَا فَإِنَّ هَذَا مِنْ بَابِ الْمُثْلَةِ فَإِنَّ الْإِكْرَاهَ عَلَى الْوَطْءِ مُثْلَةٌ فَإِنَّ الْوَطْءَ يَجْرِي مَجْرَى الْجِنَايَةِ وَلِهَذَا لَا يَخْلُو عَنْ عُقْرٍ أَوْ عُقُوبَةٍ
