[Machine] I heard Abu Wa'il saying, "Hudhayfah married a Jewish woman, so Umar wrote to him advising him to leave her. Umar expressed his fear that Muslim women would follow suit and marry non-Muslim men. This advice from Umar was based on a precautionary and disliked act. In another narration, it is mentioned that Hudhayfah wrote back asking if she was unlawful for him. Umar replied saying, "No, but I fear that you may engage in relations with non-Muslim women."  

سَمِعْتُ أَبَا وَائِلٍ يَقُولُ تَزَوَّجَ حُذَيْفَةُ ؓ يَهُودِيَّةً فَكَتَبَ إِلَيْهِ عُمَرُ ؓ أَنْ يُفَارِقَهَا فَقَالَ إِنِّي أَخْشَى أَنْ تَدَعُوا الْمُسْلِمَاتِ وَتَنْكِحُوا الْمُومِسَاتِ وَهَذَا مِنْ عُمَرَ ؓ عَلَى طَرِيقِ التَّنْزِيهِ وَالْكَرَاهَةِ فَفِي رِوَايَةٍ أُخْرَى أَنَّ حُذَيْفَةَ كَتَبَ إِلَيْهِ أَحَرَامٌ هِيَ؟ قَالَ لَا وَلَكِنِّي أَخَافُ أَنْ تُعَاطُوا الْمُومِسَاتِ مِنْهُنَّ
