339. hadíth
وَ رَوَى اِبْنُ اَلْمُغِيرَةِ عَنْ سَمَاعَةَ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ مُعْتَكِفٍ وَاقَعَ أَهْلَهُ فَقَالَ «هُوَ بِمَنْزِلَةِ مَنْ أَفْطَرَ يَوْماً مِنْ شَهْرِ رَمَضَانَ ».
It is narrated by Ibn Al-Mughira, from Sama'ah, who said: "I asked Abu Abdullah (a.s) about a person performing i'tikaf who engaged in sexual relations with their spouse. Imam (a.s) said: 'They are like one who has broken their fast on a day of Month of Ramadan.'"
