[Machine] I bear witness that Abu Huraira and Abu Sa'eed testified that they witnessed the Prophet ﷺ, and I bear witness on their behalf that he said: "When a servant says 'there is no god but Allah, and Allah is the Greatest,' his Lord, blessed and exalted, confirms his statement. Shu'bah disagreed with him and the hadith was stopped, and Abu Sa'eed Al-Khudri was not mentioned."  

الكبرى للنسائي:٩٧٧٥9775/ 9776 أَخْبَرَنَا عَمْرُو بْنُ مَنْصُورٍ قَالَ حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ عَنْ إِسْرَائِيلَ عَنْ أَبِي إِسْحَاقَ عَنِ الْأَغَرِّ قَالَ

أَشْهَدُ عَلَى أَبِي هُرَيْرَةَ وَأَبِي سَعِيدٍ أَنَّهُمَا شَهِدَا عَلَى النَّبِيِّ ﷺ وَأَنَا أَشْهَدُ عَلَيْهِمَا أَنَّهُ قَالَ إِنَّ الْعَبْدَ إِذَا قَالَ لَا إِلَهَ إِلَّا اللهُ وَاللهُ أَكْبَرُ صَدَّقَهُ رَبُّهُ تَبَارَكَ وَتَعَالَى خَالَفَهُ شُعْبَةُ فَوَقَفَ الْحَدِيثَ وَلَمْ يَذْكُرْ أَبَا سَعِيدٍ الْخُدْرِيَّ
