Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 16
الْحُسَيْنُ بْنُ سَعِيدٍ عَنْ ابْنِ أَبِي عُمَيْرٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اللهِ عَلَيْهِ السَّلَامُ قَالَ: إِذَا سَمَّيْتَ فِي الْوُضُوءِ طَهُرَ جَسَدُكَ كُلُّهُ، وَإِذَا لَمْ تُسَمِّ لَمْ يَطْهُرْ مِنْ جَسَدِكَ إِلَّا مَا مَرَّ عَلَيْهِ الْمَاءُ.
Al-Husayn ibn Sa'id, from Ibn Abi Umayr, from some of our companions, from Abu Abdullah عليه السلام, who said:
Imam Al Sadiq عليه السلام said: "If you mention the name of Allah سبحانه وتعالى during ablution, your entire body becomes purified. However, if you do not mention it, only the parts of your body that the water touches will be purified."
