٤ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ عَلِيِّ بْنِ سُلَيْمَانَ قَالَ كَتَبْتُ إِلَى الرَّجُلِ (عَلَيْهِ الْسَّلام) مَا تَقُولُ فِي صَلاَةِ التَّسْبِيحِ فِي الْمَحْمِلِ فَكَتَبَ (عَلَيْهِ الْسَّلام) إِذَا كُنْتَ مُسَافِراً فَصَلِّ.
4. Ahmad ibn Idris has narrated from Muhammad ibn Ahmad from Ali ibn Sulayman who has said the following: “I wrote to the man (Imam) , ‘What do you say about reading Salah (prayer) of Tasbih while sitting in a carriage on the back of camel?’ He wrote back, ‘If you are on a journey you can perform it (in such carriage).”’
