Chapter on I'tikaf (spiritual Retreat)
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 38
وَ رَوَى اَلْبَزَنْطِيُّ عَنْ دَاوُدَ بْنِ سِرْحَانَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «لاَ أَرَى اَلاِعْتِكَافَ إِلاَّ فِي اَلْمَسْجِدِ اَلْحَرَامِ أَوْ مَسْجِدِ اَلرَّسُولِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ أَوْ فِي مَسْجِدِ اَلْجَامِعِ وَ لاَ يَنْبَغِي لِلْمُعْتَكِفِ أَنْ يَخْرُجَ مِنَ اَلْمَسْجِدِ اَلْجَامِعِ إِلاَّ لِحَاجَةٍ لاَ بُدَّ مِنْهَا ثُمَّ لاَ يَجْلِسُ حَتَّى يَرْجِعَ وَ اَلْمَرْأَةُ مِثْلُ ذَلِكَ ».
It is narrated by Al-Bazanti, from Dawud ibn Sirhan, from Abu Abdullah عليه السلام, who said: "I do not consider i'tikaf valid except in the Sacred Mosque (Masjid al-Haram), the Mosque of the Messenger (peace and blessings be upon him and his family), or a congregational mosque. The one performing i'tikaf should not leave the congregational mosque except for a necessity that cannot be avoided, and they should not sit until they return. The same applies to women."
