Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 16
أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى عَنِ اَلْحَسَنِ بْنِ عَلِيٍّ عَنْ عَبْدِ اَللَّهِ بْنِ اَلْمُغِيرَةِ عَنْ عِيصِ بْنِ اَلْقَاسِمِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« مَنْ ذَكَرَ اِسْمَ اَللَّهِ تَعَالَى عَلَى وُضُوئِهِ فَكَأَنَّمَا اِغْتَسَلَ».
Ahmad ibn Muhammad ibn Isa, from Al-Hasan ibn Ali, from Abdullah ibn Al-Mughira, from Iys ibn Al-Qasim, from Abu Abdullah عليه السلام, who said:
Imam عليه السلام said: "Whoever mentions the name of Allah سبحانه وتعالى, the Exalted, during his ablution, it is as if he has performed a complete ritual bath (ghusl)."
