حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ سُفْيَانَ عَنْ أَبِي مَالِکٍ الْأَشْجَعِيِّ عَنْ أَبِي حَازِمٍ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا غِرَارَ فِي صَلَاةٍ وَلَا تَسْلِيمٍ قَالَ أَحْمَدُ يَعْنِي فِيمَا أَرَی أَنْ لَا تُسَلِّمَ وَلَا يُسَلَّمَ عَلَيْکَ وَيُغَرِّرُ الرَّجُلُ بِصَلَاتِهِ فَيَنْصَرِفُ وَهُوَ فِيهَا شَاکٌّ
سنن ابودوٗد · Hadith 928
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.
