سنن أبي داود#928Sahihحَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ سُفْيَانَ، عَنْ أَبِي مَالِكٍ الأَشْجَعِيِّ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ غِرَارَ فِي صَلاَةٍ وَلاَ تَسْلِيمٍ " . قَالَ أَحْمَدُ يَعْنِي فِيمَا أُرَى أَنْ لاَ تُسَلِّمَ وَلاَ يُسَلَّمَ عَلَيْكَ وَيُغَرِّرُ الرَّجُلُ بِصَلاَتِهِ فَيَنْصَرِفُ وَهُوَ فِيهَا شَاكٌّ .
Abu Hurairah reported the Prophet (ﷺ) as saying:There is no loss in prayer nor in salutation. Ahmad(b. Hanbal) said: This means, I think, that you do not salute nor you are saluted by others. The loss of a man in his prayer is that a man remains doubtful about it when he finishes it
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.
