[Machine] I heard a woman asking the Messenger of Allah ﷺ how she should deal with her garment if it is stained with blood when she becomes clean from her menstruation. He said, "If you see blood on it, scratch it off, then rub it, then wash it thoroughly with water and then pray in it."  

الدارمي:٧٩٩أَخْبَرَنَا أَحْمَدُ بْنُ خَالِدٍ حَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ عَنْ فَاطِمَةَ بِنْتِ الْمُنْذِرِ عَنْ جَدَّتِهَا أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ قَالَتْ

سَمِعْتُ امْرَأَةً وَهِيَ تَسْأَلُ رَسُولَ اللَّهِ ﷺ كَيْفَ تصْنعُ بِثوْبها إِذَا طَهُرَتْ مَنْ مَحِيضِهَا؟ قَالَ «إِنْ رَأَيْتِ فِيهِ دمًا فَحُكِّيهِ ثُمَّ اقْرُصِيهِ ثُمَّ انْضَحِي فِي سَائِرِ ثَوْبِكِ ثُمَّ صَلِّي فِيهِ»
