Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 16
أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ اِبْنِ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ اَلْحَسَنِ بْنِ رِبَاطٍ عَنْ عَبْدِ اَلْأَعْلَى مَوْلَى آلِ سَامٍ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَثَرْتُ فَانْقَطَعَ ظُفُرِي فَجَعَلْتُ عَلَى إِصْبَعِي مَرَارَةً فَكَيْفَ أَصْنَعُ بِالْوُضُوءِ قَالَ« يُعْرَفُ هَذَا وَ أَشْبَاهُهُ مِنْ كِتَابِ اَللَّهِ عَزَّ وَ جَلَّ قَالَ اَللَّهُ« مٰا جَعَلَ عَلَيْكُمْ فِي اَلدِّينِ مِنْ حَرَجٍ» اِمْسَحْ عَلَيْهِ».
Ahmad ibn Muhammad narrated from Ibn Mahbub, from Ali ibn al-Hasan ibn Ribaat, from Abdul A'la, the servant of Aal-e Sam, who said:
I said to Abu Abdillah عليه السلام: "I stumbled, and my fingernail was torn off, so I placed a bandage on my finger. How should I perform wudu (ablution)?" Imam عليه السلام said: "This and similar cases are understood from the Book of Allah سبحانه وتعالى, the Exalted. Allah سبحانه وتعالى says: 'He has not placed upon you in religion any difficulty' (Surah Al-Hajj, 22:78). So, Wipe over it."
