Yahya b Abi Kathir has reported this hadith with the same chain of transmitters and narrated:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ ، أَخْبَرَنَا عَلِيُّ بْنُ الْمُبَارَكِ ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ ، بِهَذَا الإِسْنَادِ وَقَالَ " فَإِذَا هُوَ جَالِسٌ عَلَى عَرْشٍ بَيْنَ السَّمَاءِ وَالأَرْضِ " .
And there he was sitting on the Throne between the heaven and the earth.
