[Machine] When the migrants arrived in Medina, they married from their women, but the migrants would ask for their wives' consent while the people of Medina would not. So, a man from the migrants wanted to have relations with his wife but she refused until she could ask the Prophet Mohammad ﷺ . She went to him but felt shy to ask him, so she asked Umm Salamah instead. Umm Salamah revealed the verse: "Your wives are a place of sowing of seed for you, so come to your place of cultivation however you wish" (Quran 2:223). The Prophet also said that this could only be done through one opening. Waki Ibn Sabit, who was from the Quraysh tribe, also said the same thing.
لَمَّا قَدِمَ الْمُهَاجِرُونَ الْمَدِينَةَ عَلَى الْأَنْصَارِ تَزَوَّجُوا مِنْ نِسَائِهِمْ وَكَانَ الْمُهَاجِرُونَ يُجَبُّونَ وَكَانَتِ الْأَنْصَارُ لَا تُجَبِّي فَأَرَادَ رَجُلٌ مِنَ الْمُهَاجِرِينَ امْرَأَتَهُ عَلَى ذَلِكَ فَأَبَتْ عَلَيْهِ حَتَّى تَسْأَلَ النَّبِيَّ ﷺ قَالَتْ فَأَتَتْهُ فَاسْتَحْيَتْ أَنْ تَسْأَلَهُ فَسَأَلَتْهُ أُمُّ سَلَمَةَ فَنَزَلَتْ {نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُواحَرْثَكُمْ أَنَّى شِئْتُمْ} [البقرة 223] وَقَالَ لَا إِلَّا فِي صِمَامٍ وَاحِدٍ وقَالَ وَكِيعٌ ابْنُ سَابِطٍ رَجُلٌ مِنْ قُرَيْشٍ
