4552 - وَ فِي رِوَايَةِ عَلِيِّ بْنِ رِئَابٍ عَنِ اَلْحَلَبِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ اَلرَّجُلُ يَشْتَرِي اَلْأُخْتَيْنِ فَيَطَأُ إِحْدَاهُمَا ثُمَّ يَطَأُ اَلْأُخْرَى قَالَ "إِذَا وَطِئَ اَلْأُخْرَى بِجَهَالَةٍ لَمْ تَحْرُمْ عَلَيْهِ اَلْأُولَى فَإِنْ وَطِئَ اَلْأَخِيرَةَ وَ هُوَ يَعْلَمُ أَنَّهَا تَحْرُمُ عَلَيْهِ حَرُمَتَا عَلَيْهِ جَمِيعاً".
Hadith.4552 - In a narration from Ali ibn Ri'ab, from Al-Halabi, from Abu Abdillah (as), he said: I asked him about a man who purchases two sisters and has relations with one of them, then has relations with the other. Imam (as) said: "If he had relations with the second one out of ignorance, the first does not become prohibited for him. However, if he had relations with the second one while knowing that it is prohibited, then both of them become prohibited for him."
