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.

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 ‏.‏
