This hadith has been narrated by A'raj with the same chain of transmitters (and the words are):" Whereas the person was driving a sacrificial camel which was garlanded."
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا الْمُغِيرَةُ بْنُ عَبْدِ الرَّحْمَنِ الْحِزَامِيُّ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، بِهَذَا الإِسْنَادِ وَقَالَ بَيْنَمَا رَجُلٌ يَسُوقُ بَدَنَةً مُقَلَّدَةً .
