Sunan of Abu Dawood Book 11, Hadith 1928

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَبَابَةُ، ح وَحَدَّثَنَا مَخْلَدُ بْنُ خَالِدٍ، - الْمَعْنَى - أَخْبَرَنَا عُثْمَانُ بْنُ عُمَرَ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، بِإِسْنَادِ ابْنِ حَنْبَلٍ عَنْ حَمَّادٍ، وَمَعْنَاهُ، قَالَ بِإِقَامَةٍ وَاحِدَةٍ لِكُلِّ صَلاَةٍ وَلَمْ يُنَادِ فِي الأُولَى وَلَمْ يُسَبِّحْ عَلَى أَثَرِ وَاحِدَةٍ مِنْهُمَا ‏.‏ قَالَ مَخْلَدٌ لَمْ يُنَادِ فِي وَاحِدَةٍ مِنْهُمَا ‏.‏

The aforesaid tradition has also been transmitted to the same effect by by Al Zuhri with a different chain of narrators beginning with Ibn Hanbal on the authority of Hammad. This version adds "With an iqamah for every prayer, he did not call adhan for the first prayer and he did not offer supererogatory prayer after any of them. The narrator Makhlad said "He did not call adhan for any of them."
