سنن أبي داود#5200Sahihحَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ الْهَمْدَانِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي مُعَاوِيَةُ بْنُ صَالِحٍ، عَنْ أَبِي مُوسَى، عَنْ أَبِي مَرْيَمَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ إِذَا لَقِيَ أَحَدُكُمْ أَخَاهُ فَلْيُسَلِّمْ عَلَيْهِ فَإِنْ حَالَتْ بَيْنَهُمَا شَجَرَةٌ أَوْ جِدَارٌ أَوْ حَجَرٌ ثُمَّ لَقِيَهُ فَلْيُسَلِّمْ عَلَيْهِ أَيْضًا . قَالَ مُعَاوِيَةُ وَحَدَّثَنِي عَبْدُ الْوَهَّابِ بْنُ بُخْتٍ عَنْ أَبِي الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم مِثْلَهُ سَوَاءً .
Narrated AbuHurayrah: When one of you meets his brother, he should salute him, then if he meets him again after a tree, wall or stone has come between them, he should also salute him. Mu'awiyah said: 'Abd al-Wahhab b. Bakht transmitted a similar tradition to me from Abu al-Zinad, from al-A'raj, from Abu Hurairah, from the Messenger of Allah (ﷺ)
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.
