11ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ عَبْدِ الله بْنِ جَعْفَرٍ عَنْ مُحَمَّدِ بْنِ جَزَّكٍ قَالَ كَتَبْتُ إِلَيْهِ جُعِلْتُ فِدَاكَ إِنَّ لِي جِمَالاً وَلِي قُوَّامٌ عَلَيْهَا وَقَدْ أَخْرُجُ فِيهَا إِلَى طَرِيقِ مَكَّةَ لِرَغْبَةٍ فِي الْحَجِّ أَوْ فِي النَّدْرَةِ إِلَى بَعْضِ الْمَوَاضِعِ فَهَلْ يَجِبُ عَلَيَّ التَّقْصِيرُ فِي الصَّلاَةِ وَالصِّيَامِ فَوَقَّعَ (عَلَيْهِ الْسَّلام) إِنْ كُنْتَ لاَ تَلْزَمُهَا وَلاَ تَخْرُجُ مَعَهَا فِي كُلِّ سَفَرٍ إِلاَّ إِلَى مَكَّةَ فَعَلَيْكَ تَقْصِيرٌ وَفُطُورٌ.
11. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Ja‘far from Muhammad ibn Jazzak who has said the following: “I once wrote to him (the Imam) 
, ‘I pray to Allah to keep my soul in service for your cause. I have a few camels and I have a caretaker for them. At certain times I go to them on the way to Makkah because of desire for Hajj or for al-Nadrah (rarely) in certain places. Is it necessary to perform my Salah (prayer) as complete and fast, or as reduced? He (the Imam) wrote in answer, ‘If you are not always with them and do not go on the journey with them all the time except the journey to Makkah, you must perform your Salah (prayer) as reduced and do not fast.’”
