It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that Sayyidah Khawlah bint Yasar (may Allah be pleased with her) said to the Prophet (peace and blessings be upon him): What is your view (peace and blessings be upon him) if the blood does not come out of the clothes? He (peace and blessings be upon him) said: "Water is sufficient for you, and its trace will not harm you."
Only Ibn Lahi'ah narrated it.
