Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ سَأَلَهُ أَبُو بَصِيرٍ: عَنِ اَلرَّجُلِ يُرِيدُ مَكَّةَ أَوِ اَلْمَدِينَةَ أَ يُكْرَهُ أَنْ يَخْرُجَ مِنْهُ بِالسِّلاَحِ فَقَالَ «لاَ بَأْسَ أَنْ يَخْرُجَ بِالسِّلاَحِ مِنْ بَلَدِهِ وَ لَكِنْ إِذَا دَخَلَ مَكَّةَ لَمْ يُظْهِرْهُ.
Abu Basir asked him (Abu Abdullah عليه السلام) about a man intending to travel to Mecca or Medina and whether it is disliked for him to carry weapons. Imam عليه السلام replied: "There is no harm in carrying weapons when leaving his hometown, but when he enters Mecca, he should not display them."
