Hadith 1:36
Narrated Abu Huraira (rad):
Khaula said, “O Messenger of Allah, suppose the (trace of) the blood does not go?” He said, “(Washing it with) water will suffice you and its trace won’t harm you”. [Reported by At Tirmidhi, and its Sanad (chain of narrators) is weak].
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَتْ خَوْلَةُ: { يَا رَسُولَ اَللَّهِ, فَإِنْ لَمْ يَذْهَبْ اَلدَّمُ? قَالَ: "يَكْفِيكِ اَلْمَاءُ, وَلَا يَضُرُّكِ أَثَرُهُ" } أَخْرَجَهُ اَلتِّرْمِذِيُّ, وَسَنَدُهُ ضَعِيف ٌ (41)
