Prayer During Travel
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 59
وَ مَا رَوَاهُ عَلِيُّ بْنُ يَقْطِينٍ عَنْ أَبِي اَلْحَسَنِ اَلْأَوَّلِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «كُلُّ مَنْزِلٍ مِنْ مَنَازِلِكَ لاَ تَسْتَوْطِنُهُ فَعَلَيْكَ فِيهِ اَلتَّقْصِيرُ.
Ali ibn Yaqtin reported from Abu al-Hasan the First عليه السلام who said: "For every dwelling of yours that you do not consider a permanent residence, you must shorten your prayers there."
