The time of Impurity
مُحَمَّدُ بْنُ أَبِي عَبْدِ اللَّهِ عَنْ مُعَاوِيَةَ بْنِ حُكَيْمٍ عَنْ عَبْدِ اللَّهِ بْنِ الْمُغِيرَةِ عَنْ أَبِي الْحَسَنِ الْأَوَّلِ ( عليه السلام ) فِي امْرَأَةٍ نَفِسَتْ فَتَرَكَتِ الصَّلَاةَ ثَلَاثِينَ يَوْماً ثُمَّ تَطَهَّرَتْ ثُمَّ رَأَتِ الدَّمَ بَعْدَ ذَلِكَ قَالَ تَدَعُ الصَّلَاةَ لِأَنَّ أَيَّامَهَا أَيَّامُ الطُّهْرِ وَ قَدْ جَازَتْ أَيَّامُ النِّفَاسِ
Muhammad Bin Abu Abullah, from Muawiya Bin Hukeym, from Abdullah Bin Al Mugheira,
(It has been narrated) from Abu Al-Hassan-asws the 1st regarding a woman who had post-childbirth bleeding (Nafsa’a). So she left the Salaat for thirty days, then she was clean. Then she saw blood after that. He-asws said: ‘She should leave the Salaat, because her days are the days of purity, and the days of the post-childbirth bleeding (Nafsa’a) have passed’.[1]
