Chapter on the Prayer During Travel
Tahdhīb al-Aḥkām|Volume 3|Book 2|Chapter 1
عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ سَهْلٍ عَنْ أَبِيهِ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يُصَلِّي اَلنَّافِلَةَ قَاعِداً وَ لَيْسَتْ بِهِ عِلَّةٌ فِي سَفَرٍ أَوْ حَضَرٍ قَالَ« لاَ بَأْسَ»
From him, from Ahmad ibn Muhammad, from Muhammad ibn Sahl, from his father, who said:
I asked Abu al-Hasan عليه السلام, peace be upon him, about a man who performs the supererogatory prayer (al-nafilah) sitting down, and he has no illness, whether in travel or at home. Imam عليه السلام said: “There is no harm.”
