In-book no 706حَدَّثَنَا كَثِيرُ بْنُ عُبَيْدٍ يَعْنِي الْمَذْحِجِيَّ، حَدَّثَنَا أَبُو حَيْوَةَ، عَنْ سَعِيدٍ، بِإِسْنَادِهِ وَمَعْنَاهُ زَادَ فَقَالَ " قَطَعَ صَلاَتَنَا قَطَعَ اللَّهُ أَثَرَهُ " . قَالَ أَبُو دَاوُدَ وَرَوَاهُ أَبُو مُسْهِرٍ عَنْ سَعِيدٍ قَالَ فِيهِ " قَطَعَ صَلاَتَنَا " .
This tradition as also been reported by Sa’id through the same chain of narrators and to the same effect. He added: He cut off our prayer, may Allah cut off his walking. Abu Dawud said: This version narrated by Mushir on the authority of Sa’id has: He cut off our prayer.
