Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 88
وَ رَوَى اَلْحَلَبِيُّ عَنْهُ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «إِذَا صَلَّيْتَ فِي اَلسَّفَرِ شَيْئاً مِنَ اَلصَّلَوَاتِ فِي غَيْرِ وَقْتِهَا فَلاَ يَضُرُّكَ.
It is narrated by Al-Halabi from Him (Imam Al-Sadiq عليه السلام) that He said: "If you pray any of the prayers during travel outside of its (regular) time, it will not harm you."
