A woman asked Messenger of Allah ﷺ, "O Messenger of Allah ﷺ! What should we do, if the blood of menses falls on our clothes?" Messenger of Allah ﷺ replied, "If the blood of menses falls on the garment of anyone of you, she must take hold of the blood spot, rub it, and wash it with water and then pray in (with it).  

أَنَّهَا قَالَتْ سَأَلَتِ امْرَأَةٌ رَسُولَ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِحْدَانَا إِذَا أَصَابَ ثَوْبَهَا الدَّمُ مِنَ الْحَيْضَةِ كَيْفَ تَصْنَعُ فَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَصَابَ ثَوْبَ إِحْدَاكُنَّ الدَّمُ مِنَ الْحَيْضَةِ فَلْتَقْرُصْهُ ثُمَّ لِتَنْضَحْهُ بِمَاءٍ ثُمَّ لِتُصَلِّي فِيهِ  

A woman asked the Messenger of Allah ﷺ: Messenger of Allah, what do you think if the clothe of any of us smeared with the blood of menstruation; what should she do ? He said: If (the clothe of) any of you is smeared with blood of menstruation, she should scratch it; then she should sprinkle water upon it and then she may pray.

Yahya related to me from Malik from Hisham ibn Urwa from his father from Fatima bint al-Mundhir ibn az-Zubayr that Asma bint Abu Bakr as-Siddiq said, "A woman questioned the Messenger of Allah ﷺ saying, 'If menstrual blood gets onto our clothes how do you think we should deal with it?' The Messenger of Allah ﷺ said, 'If menstrual blood gets onto your clothes you should wash them, and sprinkle them with water before you pray in them.' "
