٤ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ الْحَسَنِ بْنِ رِبَاطٍ عَنْ عَبْدِ الأعْلَى مَوْلَى آلِ سَامٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) عَثَرْتُ فَانْقَطَعَ ظُفُرِي فَجَعَلْتُ عَلَى إِصْبَعِي مَرَارَةً فَكَيْفَ أَصْنَعُ بِالْوُضُوءِ قَالَ يُعْرَفُ هَذَا وَأَشْبَاهُهُ مِنْ كِتَابِ الله عَزَّ وَجَلَّ ما جَعَلَ عَلَيْكُمْ فِي الدِّينِ مِنْ حَرَجٍ امْسَحْ عَلَيْهِ. 
4. A number of our people have narrated from Ahmad ibn Muhammad from ibn Mahbub from Ali ibn al-Hassan ibn Ribat from ‘Abd al-A’la’, Mawla’ Ale Sam who has said the following: “I once said to abu ‘Abd Allah , ‘I slipped and my toe nail suffered a cut. I have placed a bitter ointment on my toe. How should I take Wudu’?’ He (the Imam) said, ‘This and such matters are learned from the book of Allah, most Majestic, most Glorious, which says, “Allah has not sanctioned anything in religion which may cause you hardships.” You must wipe over the bandage.’””
