341. hadíth
وَ رَوَى اِبْنُ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلْمُعْتَكِفَةِ إِذَا طَمِثَتْ قَالَ «تَرْجِعُ إِلَى بَيْتِهَا فَإِذَا طَهُرَتْ رَجَعَتْ فَقَضَتْ مَا عَلَيْهَا ».
It is narrated by Ibn Mahbub, from Abu Ayyub, from Abu Basir, from Abu Abdullah (a.s), regarding a woman performing i'tikaf who experiences menstruation. Imam (a.s) said: "She should return to her home, and when she becomes pure, she should return and make up for what she missed."
