Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ فِي رِوَايَةِ حَرِيزِ بْنِ عَبْدِ اَللَّهِ عَنْهُ عَلَيْهِ اَلسَّلاَمُ قَالَ: «لاَ يَنْبَغِي أَنْ يَدْخُلَ اَلْحَرَمَ بِسِلاَحٍ إِلاَّ أَنْ يُدْخِلَهُ فِي جُوَالِقٍ أَوْ يُغَيِّبَهُ يَعْنِي حَتَّى يَلُفَّ عَلَى اَلْحَدِيدِ شَيْئاً».
In a narration from Hariz ibn Abdullah, from him (Imam Abu Abdullah عليه السلام): "It is not appropriate to enter the Haram with a weapon unless it is placed in a sack or concealed - meaning, the blade should be wrapped in something."
