Congregational Prayer and Its Virtue
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَ رَوَى دَاوُدُ بْنُ اَلْحُصَيْنِ عَنْهُ أَنَّهُ قَالَ: «لاَ يَؤُمُّ اَلْحَضَرِيُّ اَلْمُسَافِرَ وَ لاَ يَؤُمُّ اَلْمُسَافِرُ اَلْحَضَرِيَّ فَإِنِ اُبْتُلِيَ اَلرَّجُلُ بِشَيْءٍ مِنْ ذَلِكَ فَأَمَّ قَوْماً حَاضِرِينَ فَإِذَا أَتَمَّ اَلرَّكْعَتَيْنِ سَلَّمَ ثُمَّ أَخَذَ بِيَدِ أَحَدِهِمْ فَقَدَّمَهُ فَأَمَّهُمْ فَإِذَا صَلَّى اَلْمُسَافِرُ خَلْفَ قَوْمٍ حُضُورٍ فَلْيُتِمَّ صَلاَتَهُ رَكْعَتَيْنِ وَ يُسَلِّمُ.
Dawud ibn Al-Hussain narrated that the Imam عليه السلام said: "A resident (non-traveler) should not lead a traveler, nor should a traveler lead a resident. If a man finds himself in a situation where he must lead a congregation of residents and completes two rak'ahs, he should then offer the taslim (salutation of peace), take the hand of one of the residents, and place him to lead the rest. When a traveler prays behind a group of residents, he should complete his prayer with two rak'ahs and then offer the taslim."
