Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 15
اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا سَمَّيْتَ فِي اَلْوُضُوءِ طَهُرَ جَسَدُكَ كُلُّهُ وَ إِذَا لَمْ تُسَمِّ لَمْ يَطْهُرْ مِنْ جَسَدِكَ إِلاَّ مَا مَرَّ عَلَيْهِ اَلْمَاءُ».
Al-Husayn ibn Sa'id, from Ibn Abi Umayr, from some of our companions, from Abu Abdullah عليه السلام, said:
Imam عليه السلام said: "If you mention the name of Allah سبحانه وتعالى (say Bismillah) during wudu (ablution), your entire body becomes purified. However, if you do not mention the name of Allah سبحانه وتعالى, only the parts of your body over which (wudu) water passes will be purified."
