فَأَمَّا مَا رَوَاهُ مُحَمَّدُ بْنُ يَحْيَى رَفَعَهُ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلَّذِي يَخْضِبُ رَأْسَهُ بِالْحِنَّاءِ ثُمَّ يَبْدُو لَهُ فِي اَلْوُضُوءِ قَالَ« لاَ يَجُوزُ حَتَّى يُصِيبَ بَشَرَةَ رَأْسِهِ اَلْمَاءُ».
Narrated by Muhammad ibn Yahya, who raised it to Abu Abdullah عليه السلام, regarding someone who dyes his hair with henna and then decides to perform ablution. Imam عليه السلام said: "It is not valid until the water touches the skin of his head."
