وَعَنْ أُمِّ سَلَمَةَ رَضِيَ اَللَّهُ عَنْهَا قَالَتْ: "قُلْتُ: يَا رَسُولَ اَللَّهِ إِنِّي اِمْرَأَةٌ أَشُدُّ شَعْرَ رَأْسِي, أَفَأَنْقُضُهُ لِغُسْلِ اَلْجَنَابَةِ? وَفِي رِوَايَةٍ: وَالْحَيْضَةِ? فَقَالَ: "لَا, إِنَّمَا يَكْفِيكِ أَنْ تَحْثِي عَلَى رَأْسِكِ ثَلَاثَ حَثَيَاتٍ" رَوَاهُ مُسْلِمٌ
Narrated Umm Salamah (RAA):
I said, “O Messenger of Allah, I am a woman who keeps her hair closely plaited. Do I have to undo them for Ghusl after sexual intercourse?” In another narration, “and after the end of menses?” He replied (ﷺ), “No, is it enough for you to throw three handfuls of water over your head.” Related by Muslim.
