A woman came to the Messenger of Allah ﷺ and said: What should one do if the blood of menses smears the garment of one amongst us? He (the Holy Prophet) replied: She should scrape it, then rub it with water, then pour water over it and then offer prayer in it. (Using translation from Muslim 291a)
جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ إِحْدَانَا يُصِيبُ ثَوْبَهَا مِنْ دَمِ الْحَيْضَةِ فَكَيْفَ تَصْنَعُ بِهِ؟ قَالَ تَحُتُّهُ ثُمَّ تَقْرُصُهُ بِالْمَاءِ ثُمَّ تَنْضَحُهُ ثُمَّ تُصَلِّي فِيهِ
