Al-Agharr Abu Muslim narrated that he bears witness from Abu Sa’eed Al-Khudri and Abu Hurairah, that they bear witness that :

the Prophet ﷺ said: “Whoever says: ‘There is none worthy of worship except Allah, and Allah is the Greatest, (La Ilaha Illallah, Wa Allahu Akbar)’ His Lord affirms his statement and says: ‘There is none worthy of worship except Me, and I am the Greatest,’ and when he say: ‘There is none worthy of worship except for Allah, Alone, (La Ilaha Illallah, Wahdahu)’ Allah says: ‘There is none worthy of worship except for Me and I am Alone.’ And when he say: ‘There is none worthy of worship except for Allah, Alone, without partner, (La Ilaha Illallah, Wahdahu La Sharika Lahu)’ Allah says: ‘There is none worthy of worship except Me, Alone, I have no partner.’ And when he say: ‘There is none worthy of worship except for Allah, to Him belongs all that exists, and to Him is the praise, (La Ilaha Illallah, Lahul-Mulku Wa Lahul-Hamdu)’ Allah says: ‘There is none worthy of worship except Me, to Me belongs all that exists, and to Me is the praise.’ And when he says: ‘There is none worthy of worship except Allah, and there is no might or power except by Allah, (La Ilaha Illallah, Wa La Hawla Wa La Quwwata Illa Billah)’ Allah says: ‘There is none worthy of worship except Me, and there is no might or power except by Me.’” And he used to say: “Whoever says it in his illness, then dies, the Fire shall not consume him.”

حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ مُحَمَّدِ بْنِ جُحَادَةَ، حَدَّثَنَا عَبْدُ الْجَبَّارِ بْنُ عَبَّاسٍ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَغَرِّ أَبِي مُسْلِمٍ، قَالَ أَشْهَدُ عَلَى أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ أَنَّهُمَا شَهِدَا عَلَى النَّبِيِّ ﷺ قَالَ " مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ . صَدَّقَهُ رَبُّهُ فَقَالَ لاَ إِلَهَ إِلاَّ أَنَا وَأَنَا أَكْبَرُ . وَإِذَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ . قَالَ يَقُولُ اللَّهُ لاَ إِلَهَ إِلاَّ أَنَا وَأَنَا وَحْدِي . وَإِذَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ . قَالَ اللَّهُ لاَ إِلَهَ إِلاَّ أَنَا وَحْدِي لاَ شَرِيكَ لِي . وَإِذَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ . قَالَ اللَّهُ لاَ إِلَهَ إِلاَّ أَنَا لِيَ الْمُلْكُ وَلِيَ الْحَمْدُ . وَإِذَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ . قَالَ اللَّهُ لاَ إِلَهَ إِلاَّ أَنَا وَلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِي . وَكَانَ يَقُولُ مَنْ قَالَهَا فِي مَرَضِهِ ثُمَّ مَاتَ لَمْ تَطْعَمْهُ النَّارُ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . وَقَدْ رَوَاهُ شُعْبَةُ عَنْ أَبِي إِسْحَاقَ، عَنِ الأَغَرِّ أَبِي مُسْلِمٍ، عَنْ أَبِي هُرَيْرَةَ، وَأَبِي، سَعِيدٍ بِنَحْوِ هَذَا الْحَدِيثِ بِمَعْنَاهُ وَلَمَ يَرْفَعْهُ شُعْبَةُ . حَدَّثَنَا بِذَلِكَ، بُنْدَارٌ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، بِهَذَا .
