Chapter on Acts That Necessitate Purification
Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 14
اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ: قُلْتُ لِأَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ اَلرَّجُلُ يُقَلِّمُ أَظْفَارَهُ وَ يَجُزُّ شَارِبَهُ وَ يَأْخُذُ مِنْ شَعْرِ لِحْيَتِهِ وَ رَأْسِهِ هَلْ يَنْقُضُ ذَلِكَ وُضُوءَهُ فَقَالَ« يَا زُرَارَةُ كُلُّ هَذَا سُنَّةٌ وَ اَلْوُضُوءُ فَرِيضَةٌ وَ لَيْسَ شَيْءٌ مِنَ اَلسُّنَّةِ يَنْقُضُ اَلْفَرِيضَةَ وَ إِنَّ ذَلِكَ لَيَزِيدُهُ تَطْهِيراً».
Narrated from Al-Husayn ibn Sa'id, from Hammad ibn Isa, from Hariz, from Zurara:
I asked Abu Ja'far عليه السلام: “If a man trims his nails, cuts his mustache, or takes something from the hair of his beard or head, does that invalidate his wudu (ablution)?” Imam عليه السلام replied: "O Zurara, all of this is Sunnah, and wudu is a religious obligation. Nothing from the Sunnah invalidates the obligation. In fact, doing these acts increases one in purity."
