Hadith 11772745 - وَ سَأَلَهُ مُعَاوِيَةُ بْنُ عَمَّارٍ : عَنْ رَجُلٍ مُتَمَتِّعٍ وَقَعَ عَلَى اِمْرَأَتِهِ وَ لَمْ يُقَصِّرْ قَالَ «يَنْحَرُ جَزُوراً وَ قَدْ خَشِيتُ أَنْ يَكُونَ قَدْ ثُلِمَ حَجُّهُ إِنْ كَانَ عَالِماً وَ إِنْ كَانَ جَاهِلاً فَلاَ شَيْءَ عَلَيْهِ» قَالَ وَ قُلْتُ لَهُ مُتَمَتِّعٌ قَرَضَ مِنْ أَظْفَارِهِ بِأَسْنَانِهِ وَ أَخَذَ مِنْ شَعْرِهِ بِمِشْقَصٍ فَقَالَ «لاَ بَأْسَ بِهِ لَيْسَ كُلُّ أَحَدٍ يَجِدُ اَلْجَلَمَ ».
Hadith.2745 - Mu'awiyah ibn Ammar asked Abu Abdullah (as) about a man performing tamattu‘ who had intercourse with his wife before trimming his hair.
Imam (as) said: "He must slaughter a camel. I fear that his Hajj may be invalid if he acted knowingly. However, if he acted out of ignorance, there is no penalty upon him."
Mu'awiyah also said: I asked him about a person performing tamattu‘ who bites their nails with their teeth or trims their hair using a sharp-edged tool.
Imam (as) said: "There is no harm in it. Not everyone has access to scissors."
