Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 38
رَوَى اَلْحَلَبِيُّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «لاَ اِعْتِكَافَ إِلاَّ بِصَوْمٍ فِي مَسْجِدِ اَلْجَامِعِ ».
It is narrated by Al-Halabi from Abu Abdullah عليه السلام that he said: "There is no valid i'tikaf (spiritual retreat) except with fasting and in a congregational mosque."
