Tahdhīb al-Aḥkām|Volume 3|Book 2|Chapter 1
عَنْهُ عَنْ مُحَمَّدِ بْنِ عِيسَى اَلْعُبَيْدِيِّ عَنْ سُلَيْمَانَ بْنِ حَفْصٍ اَلْمَرْوَزِيِّ قَالَ قَالَ اَلْفَقِيهُ اَلْعَسْكَرِيُّ عَلَيْهِ اَلسَّلاَمُ:« يَجِبُ عَلَى اَلْمُسَافِرِ أَنْ يَقُولَ فِي دُبُرِ كُلِّ صَلاَةٍ يُقَصِّرُ فِيهَا سُبْحَانَ اَللَّهِ وَ اَلْحَمْدُ لِلَّهِ وَ لاَ إِلَهَ إِلاَّ اَللَّهُ وَ اَللَّهُ أَكْبَرُ ثَلاَثِينَ مَرَّةً لِتَمَامِ اَلصَّلاَةِ»
From him, from Muhammad ibn Isa al-‘Ubaydi, from Sulayman ibn Hafs al-Marwazi, who said:
The jurist (faqih) of ‘Askar (Imam al-Hadi عليه السلام), peace be upon him, said: “It is obligatory upon the traveller to say at the end of every prayer in which he shortens: ‘Subhana Allah, wal-hamdu lillah, wa la ilaha illa Allah, wallahu akbar’ , thirty times to complete the prayer.”
