a woman asked the Prophet about a garment that was touched by some menstrual blood. So Messenger of Allah said: "Remove it, and scrub it, then rinse it and pray in it"  

أَنَّ امْرَأَةً سَأَلَتِ النَّبِيَّ ﷺ عَنِ الثَّوْبِ يُصِيبُهُ الدَّمُ مِنَ الْحَيْضَةِ فَقَالَ رَسُولُ اللَّهِ ﷺ حُتِّيهِ ثُمَّ اقْرُصِيهِ بِالْمَاءِ ثُمَّ رُشِّيهِ وَصَلِّي فِيهِ قَالَ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَأُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ
