صحيح ابن خزيمه
Sahih Ibn Khuzaymah
جماع أبواب تطهير الثياب بالغسل من الأنجاسChapters on Purifying Clothes from Impurities
(216) بَابُ اسْتِحْبَابِ غَسْلِ دَمِ الْحَيْضِ مِنَ الثَّوْبِ بِالْمَاءِ وَالسِّدْرِ، وَحَكِّهِ بِالْأَضْلَاعِ،Chapter 216: Recommendation to wash menstrual blood from clothing with water and lotus leaves, and to scrub with ribs
Hadith Q277
إِذْ هُوَ أَحْرَى أَنْ يَذْهَبَ أَثَرُهُ مِنَ الثَّوْبِ إِذَا حُكَّ بِالضِّلَعِ، وَغُسِلَ بِالسِّدْرِ مَعَ الْمَاءِ، مِنْ أَنْ يُغْسَلَ بِالْمَاءِ بَحْتًا.
Because instead of washing with water alone, when it is scraped with wood and washed with water and lotus, it is more effective and efficient in removing the trace of blood.
