2588 - وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ : «إِنْ وَقَعْتَ عَلَى أَهْلِكَ بَعْدَ مَا تَعْقِدُ لِلْإِحْرَامِ وَ قَبْلَ أَنْ تُلَبِّيَ فَلاَ شَيْءَ عَلَيْكَ وَ إِنْ جَامَعْتَ وَ أَنْتَ مُحْرِمٌ قَبْلَ أَنْ تَقِفَ بِالْمَشْعَرِ فَعَلَيْكَ بَدَنَةٌ وَ اَلْحَجُّ مِنْ قَابِلٍ وَ إِنْ جَامَعْتَ بَعْدَ وُقُوفِكَ بِالْمَشْعَرِ فَعَلَيْكَ بَدَنَةٌ وَ لَيْسَ عَلَيْكَ اَلْحَجُّ مِنْ قَابِلٍ وَ إِنْ كُنْتَ نَاسِياً أَوْ سَاهِياً أَوْ جَاهِلاً فَلاَ شَيْءَ عَلَيْكَ».
Hadith.2588 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "If you have intercourse with your spouse after entering the state of Ihram but before reciting the Talbiyah, there is nothing upon you. If you have intercourse while in the state of Ihram before standing at al-Mash'ar, you must offer a camel as a sacrifice and repeat the Hajj in the following year. If you have intercourse after standing at al-Mash'ar, you must offer a camel, but repeating the Hajj is not required. If you do so out of forgetfulness, negligence, or ignorance, there is nothing upon you."
