12ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ ابْنِ أَبِي نَصْرٍ قَالَ قُلْتُ لأَبِي الْحَسَنِ الرِّضَا (عَلَيْهِ السَّلاَم)
إِنَّا حِينَ نَفَرْنَا مِنْ مِنًى أَقَمْنَا أَيَّاماً ثُمَّ حَلَقْتُ رَأْسِي طَلَبَ التَّلَذُّذِ فَدَخَلَنِي مِنْ ذَلِكَ شَيْءٌ فَقَالَ كَانَ أَبُو الْحَسَنِ (صلَّى اللهُ عَلَيْهِ وَآلِه) إِذَا خَرَجَ مِنْ مَكَّةَ فَأُتِيَ بِثِيَابِهِ حَلَقَ رَأْسَهُ قَالَ وَقَالَ فِي قَوْلِ الله عَزَّ وَجَلَّ ثُمَّ لْيَقْضُوا تَفَثَهُمْ وَلْيُوفُوا نُذُورَهُمْ قَالَ التَّفَثُ تَقْلِيمُ الأَظْفَارِ وَطَرْحُ الْوَسَخِ وَطَرْحُ الإِحْرَامِ.
12. Ahmad ibn Muhammad has narrated from ibn abu Nasr who has said the following: “I once asked abu al-Hassan, al-Rida’ 
, about our case of leaving Mina’ and staying several days, then shaving my head for pleasure that raised a question in my mind. He (the Imam) said that
when abu al-Hassan ‘Alayhi al-Salam, left Makkah, his clothes were brought to him and he shaved his head and said that in the words of Allah, most Majestic, most Glorious, ‘. . . then they must spruce up and fulfill their vows. . .’ (22:29) ‘Tafath’ means cutting the finger nails, removing dirt and (clothes of) Ihram.’”
