This hadith is listed as number 2649 in Maktaba Shamila
وحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ ، وَعُثْمَانُ بْنُ أَبِي شَيْبَةَ ، قَالَا : حَدَّثَنَا جَرِيرٌ ، عَنِ الْأَعْمَشِ بِهَذَا الْإِسْنَادِ ، وَقَالَا : " فَلَمَّا نَزَلَ رَمَضَانُ تَرَكَهُ " .
This hadith has been narrated from Jarir on the authority of A'mash with the same chain of transmitters and he said (these words with a little bit of variation from the previous hadith): When (fasting) in Ramadan was (made) obligatory, he abandoned it (the practice of observing fast on Ashura).
