"I said, O Messenger of Allah! I am a woman with tight braids. Should I undo them when I take a bath to cleanse myself from the state of sexual impurity?" He said: "Rather it is sufficient for you to pour three handfuls of water over yourself, and you will be purified," or he said: "In that case you would have become purified." (Using translation from Ibn Mājah 603)
قُلْتُ يَا رَسُولَ اللهِ إِنِّي امْرَأَةٌ أَشَدُّ ضَفْرَ رَأْسِي أَفَأَنْقُضُهُ لِغُسْلِ الْجَنَابَةِ قَالَ لَا إِنَّمَا يَكْفِيكِ أَنْ تَحْثِي عَلَيْهِ ثَلَاثَ حَثَيَاتٍ ثُمَّ تُفِيضِي عَلَيْكِ الْمَاءَ فَتَطْهُرِي أَوْ قَالَ فَإِذَا أَنْتِ قَدْ طَهُرْتِ
