The Book of Prayer - Travellers
وَحَدَّثَنَاهُ يَحْيَى بْنُ حَبِيبٍ، حَدَّثَنَا خَالِدٌ يَعْنِي ابْنَ الْحَارِثِ، ح وَحَدَّثَنَا ابْنُ الْمُثَنَّى، قَالَ حَدَّثَنِي عَبْدُ الصَّمَدِ، قَالاَ حَدَّثَنَا شُعْبَةُ، بِهَذَا الإِسْنَادِ وَلَمْ يَقُولاَ فِي الْحَدِيثِ بِمِنًى . وَلَكِنْ قَالاَ صَلَّى فِي السَّفَرِ .This hadith has been narrated by Shu'ba with the same chain of transmitters but no mention has been made of Mina, but they (the narrators) only said:He prayed while travelling
From Sahih Muslim, whose reports the scholars accept as authentic.
