Prayer During Travel
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 59
وَ رَوَى سَيْفٌ اَلتَّمَّارُ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قَالَ لَهُ بَعْضُ أَصْحَابِنَا كُنَّا نَقْضِي صَلاَةَ اَلنَّهَارِ إِذَا نَزَلْنَا بَيْنَ اَلْمَغْرِبِ وَ اَلْعِشَاءِ اَلْآخِرَةِ فَقَالَ «لاَ اَللَّهُ أَعْلَمُ بِعِبَادِهِ حِينَ رَخَّصَ إِنَّمَا فَرَضَ اَللَّهُ عَزَّ وَ جَلَّ عَلَى اَلْمُسَافِرِ رَكْعَتَيْنِ لاَ قَبْلَهُمَا وَ لاَ بَعْدَهُمَا شَيْءٌ إِلاَّ صَلاَةُ اَللَّيْلِ عَلَى بَعِيرِكَ حَيْثُ تَوَجَّهَ بِكَ.
Saif al-Tammar narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام that one of our companions said to him: "We used to make up the daytime prayers when we would stop between Maghrib (evening prayer) and Isha (night prayer)." He عليه السلام replied: "No, Allah سبحانه وتعالى knows His servants best when He granted the concession. Allah سبحانه وتعالى the Mighty and Majestic has prescribed for the traveler two rak'ahs (units of prayer); there is nothing before or after them except for the night prayer while you are on your mount, wherever it may take you”.
