Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 4
وَ قَدْ رُوِيَ مِثْلُ هَذَا عَنْ أَمِيرِ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ:« مَا أُنْزِلَ اَلْقُرْآنُ إِلاَّ بِالْمَسْحِ».
A similar statement was also narrated from Commander of the Faithful عليه السلام, who said: "The Quran was revealed only with (instructions of) wiping."
