Al-Kāfi - The Book of Hayd (menses) Chapter: Women Find Hayd Blood after the Coming of the Time for a Salah (Prayer) Before Performing It Or Become Clean Before the Coming of the Time for a Salah (Prayer) But Are Too Lazy for Ghusl (bath) َحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ عُبَيْدِ بْنِ زُرَارَةَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلا٠) قَالَ قَالَ أَيُّ٠ْرَأَةٌ رَأَتِ الطُّهْرَ وَهِيَ قَادِرَةٌ عَلَى أَنْ تَغْتَسِلَ فِي وَقْتِ صَلاَةٍ فَفَرَّطَتْ فِيهَا حَتَّى يَدْخُلَ وَقْتُ صَلاَةٍ أُخْرَى كَانَ عَلَيْهَا قَضَاءُ تِلْكَ الصَّلاَةِ الَّتِي فَرَّطَتْ فِيهَا وَإِنْ رَأَتِ الطُّهْرَ فِي وَقْتِ صَلاَةٍ فَقَا٠َتْ فِي تَهْيِئَةِ ذَلِكَ فَجَازَ وَقْتُ صَلاَةٍ وَدَخَلَ وَقْتُ صَلاَةٍ أُخْرَى فَلَيْسَ عَلَيْهَا قَضَاءٌ وَتُصَلِّي الصَّلاَةَ الَّتِي دَخَلَ وَقْتُهَا.

If she finds herself clean in the time of a Salah (prayer), begins to prepare, but the time for that Salah (prayer) expires and it becomes time for another Salah (prayer), Qada’ (compensatory prayer) of such Salah (prayer) is not obligatory on her. She must perform only that Salah (prayer) for which it has become time.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (13/246))
