Nabi memerintahkan untuk mencuci pakaian dan membersihkannya dari najis sebelum shalat
Imam Nasa'i : 291أَخْبَرَنَا يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ عَنْ حَمَّادِ بْنِ زَيْدٍ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ فَاطِمَةَ بِنْتِ الْمُنْذِرِ عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ وَكَانَتْ تَكُونُ فِي حَجْرِهَاأَنَّ امْرَأَةً اسْتَفْتَتْ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ دَمِ الْحَيْضِ يُصِيبُ الثَّوْبَ فَقَالَ حُتِّيهِ ثُمَّ اقْرُصِيهِ بِالْمَاءِ ثُمَّ انْضَحِيهِ وَصَلِّي فِيهِ
Narrated to us [Yahya bin Habib bin Arabi] from [Hammad bin Zaid] from [Hisyam bin Urwah] from [Fathimah bint Al Mundzir] from [Asma' bint Abu Bakr] - she was in her room - that a woman asked for a fatwa from Rasulullah peace be upon him about menstrual blood staining clothes? He then said, 'Scratch and scrape it with your nails, then sprinkle it with water, then pray with the cloth."
