[Machine] 'Omar ibn al-Khattab came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, I am destroyed." He said, "What has destroyed you?" 'Omar said, "I turned my mount during the night and it did not respond to me in any way." Then Allah revealed to him, {Your wives are a place of sowing of seed for you}[Surah Al-Baqarah 2:223]. Face it and turn away from it, and fear Allah in regards to menstruation."
جَاءَ عُمَرُ بْنُ الْخَطَّابِ ؓ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ هَلَكْتُ قَالَ وَمَا الَّذِي أَهْلَكَكَ؟ قَالَ حَوَّلْتُ رَحْلِيَ اللَّيْلَةَ فَلَمْ يَرُدَّ عَلَيْهِ شَيْئًا ثُمَّ أَوْحَى اللهُ إِلَيْهِ {نِسَاؤُكُمْ حَرْثٌ لَكُمْ} [البقرة 223] أَقْبِلْ وَأَدْبِرْ وَاتَّقِ الدُّبُرَ وَالْحَيْضَةَ
