"I asked the Messenger of Allah about menstrual blood that gets on clothing. He said, 'Wash it with water and lote leaves, and rub it, even with a piece of stick.'" (Using translation from Ibn Mājah 628)
سَأَلْتُ رَسُولَ اللهِ ﷺ عَنْ دَمِ الْحَيْضِ يُصِيبُ الثَّوْبَ فَقَالَ اغْسِلِيهِ بِمَاءٍ وَسِدْرٍ وَحُكِّيهِ بِضِلَعٍ
