سنن أبي داود#916Sahihحَدَّثَنَا الرَّبِيعُ بْنُ نَافِعٍ، حَدَّثَنَا مُعَاوِيَةُ، - يَعْنِي ابْنَ سَلاَّمٍ - عَنْ زَيْدٍ، أَنَّهُ سَمِعَ أَبَا سَلاَّمٍ، قَالَ حَدَّثَنِي السَّلُولِيُّ، - هُوَ أَبُو كَبْشَةَ - عَنْ سَهْلِ ابْنِ الْحَنْظَلِيَّةِ، قَالَ ثُوِّبَ بِالصَّلاَةِ - يَعْنِي صَلاَةَ الصُّبْحِ - فَجَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي وَهُوَ يَلْتَفِتُ إِلَى الشِّعْبِ . قَالَ أَبُو دَاوُدَ وَكَانَ أَرْسَلَ فَارِسًا إِلَى الشِّعْبِ مِنَ اللَّيْلِ يَحْرُسُ .
Narrated Sahl ibn al-Hanzaliyyah: The iqamah for the morning prayer was pronounced and the Messenger of Allah (ﷺ) began to offer prayer while he was looking at the mountain-pass. (AbuDawud elaborated that the Prophet had sent a horseman to the mountain-pass at night in order to keep watch)
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.
