This hadith has been narrated on the authority of 'Ubaidullah with the same chain of transmitter but with the addition of the words:
وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى ، وَعُبَيْدُ اللَّهِ بْنُ سَعِيدٍ ، قَالاَ حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنْ عُبَيْدِ اللَّهِ ، بِهَذَا الإِسْنَادِ فِي مَعْنَى حَدِيثِ أَبِي أُسَامَةَ وَزَادَ قَالَ فَتَرَكَ الصَّلاَةَ عَلَيْهِمْ .
" He abandoned saying prayer over the hypocrites who had died."
