Hadith 5312102 - وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ قَالَ: سَأَلْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْمُعْتَكِفِ يُجَامِعُ قَالَ «إِذَا فَعَلَ ذَلِكَ فَعَلَيْهِ مَا عَلَى اَلْمُظَاهِرِ ».
وَ قَدْ رُوِيَ: «أَنَّهُ إِنْ جَامَعَ فِي اَللَّيْلِ فَعَلَيْهِ كَفَّارَةٌ وَاحِدَةٌ وَ إِنْ جَامَعَ بِالنَّهَارِ فَعَلَيْهِ كَفَّارَتَانِ.
Hadith.2102 - It is narrated by Al-Hasan ibn Mahbub, from Ali ibn Ri'ab, from Zurara, who said:
"I asked Abu Ja'far (as) about the ruling on an individual performing i'tikaf who engages in sexual relations.
Imam (as) said: 'If they do so, they incur the same penalty as one who has taken a vow of zihar (atonement).'"
It has also been narrated: "If they engage in sexual relations during the night, they must pay one expiation. However, if they engage in sexual relations during the day, they must pay two expiations."
