Sunan Abi Dawud 1927

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا حَمَّادُ بْنُ خَالِدٍ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، بِإِسْنَادِهِ وَمَعْنَاهُ وَقَالَ بِإِقَامَةٍ إِقَامَةٍ جَمَعَ بَيْنَهُمَا ‏.‏ قَالَ أَحْمَدُ قَالَ وَكِيعٌ صَلَّى كُلَّ صَلاَةٍ بِإِقَامَةٍ ‏.‏

The aforesaid tradition has been transmitted by Al Zuhri through a different chain of narrators. This version adds “Each prayer with an iqamah”. Ahmad reported on the authority of Waki’ “he offered each prayer with a single iqamah.”
