13ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ بَعْضِ أَصْحَابِنَا عَنْ عَلِيِّ بْنِ عُقْبَةَ عَنْ مُوسَى بْنِ أُكَيْلٍ النُّمَيْرِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ
سَأَلْتُهُ عَنِ الرَّجُلِ يَكُونُ فِي السَّفَرِ وَمَعَهُ السِّكِّينُ فِي خُفِّهِ لاَ يَسْتَغْنِي عَنْهَا أَوْ فِي سَرَاوِيلِهِ مَشْدُوداً وَالْمِفْتَاحُ يَخَافُ عَلَيْهِ الضَّيْعَةَ أَوْ فِي وَسَطِهِ الْمِنْطَقَةُ فِيهَا حَدِيدٌ قَالَ لاَ بَأْسَ بِالسِّكِّينِ وَالْمِنْطَقَةِ لِلْمُسَافِرِ فِي وَقْتِ ضَرُورَةٍ وَكَذَلِكَ الْمِفْتَاحُ يَخَافُ عَلَيْهِ أَوْ فِي النِّسْيَانِ وَلاَ بَأْسَ بِالسَّيْفِ وَكَذَلِكَ آلَةُ السِّلاَحِ فِي الْحَرْبِ وَفِي غَيْرِ ذَلِكَ لاَ تَجُوزُ الصَّلاَةُ فِي شَيْءٍ مِنَ الْحَدِيدِ فَإِنَّهُ نَجَسٌ مَمْسُوخٌ.
13. Muhammad ibn Yahya has narrated from certain persons of our people from Ali ibn ‘Uqbah from Musa ibn ‘Ukayl al-Numayriy who has said the following:
“I once asked abu ‘Abd Allah 
, about a man who on a journey has a knife in his slipper without which he cannot do anything or it is in his pant, and a key which he is afraid of losing it, or that around his midsection is a belt in which there is iron. He (the Imam) said, ‘It is not an offense to have a knife, or a belt for a traveler in case he needs them as well as a key for which one is afraid about forgetting it. It is not an offense to have a sword or weapons during a war and in other times. It is not permissible to perform Salah (prayer) with iron; it is Najis (unclean) and metamorphosed. ’ ”
