سنن أبي داود#1927Sahihحَدَّثَنَا 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.”
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Our source also lists this ruling under Muhammad Muhyi Al-Din Abdul Hamid, the editor of the printed edition it was taken from. It is al-Albani's ruling printed again, so it is counted once.
