Never a Prophet had been sent before me by Allah towards his nation who had not among his people (his) disciples and companions who followed his ways and obeyed his command. Then there came after them their successors who said whatever they did not practise, and practised whatever they were not commanded to do. He who strove against them with his hand was a believer: he who strove against them with his tongue was a believer, and he who strove against them with his heart was a believer and beyond that there is no faith even to the extent of a mustard seed. Abu Rafi' said: I narrated this hadith to 'Abdullah b. 'Umar; he contradicted me. There happened to come 'Abdullah b. Mas'ud who stayed at Qanat, and 'Abdullah b 'Umar wanted me to accompany him for visiting him (as 'Abdullah b. Mas'ud was ailing), so I went along with him and as we sat (before him) I asked Ibn Mas'ud about this hadith. He narrated it in the same way as I narrated it to Ibn 'Umar.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَا مِنْ نَبِيٍّ بَعَثَهُ اللَّهُ فِي أُمَّةٍ قَبْلِي إِلاَّ كَانَ لَهُ مِنْ أُمَّتِهِ حَوَارِيُّونَ وَأَصْحَابٌ يَأْخُذُونَ بِسُنَّتِهِ وَيَقْتَدُونَ بِأَمْرِهِ ثُمَّ إِنَّهَا تَخْلُفُ مِنْ بَعْدِهِمْ خُلُوفٌ يَقُولُونَ مَا لاَ يَفْعَلُونَ وَيَفْعَلُونَ مَا لاَ يُؤْمَرُونَ فَمَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِلِسَانِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِقَلْبِهِ فَهُوَ مُؤْمِنٌ وَلَيْسَ وَرَاءَ ذَلِكَ مِنَ الإِيمَانِ حَبَّةُ خَرْدَلٍ قَالَ أَبُو رَافِعٍ فَحَدَّثْتُهُ عَبْدَ اللَّهِ بْنَ عُمَرَ فَأَنْكَرَهُ عَلَىَّ فَقَدِمَ ابْنُ مَسْعُودٍ فَنَزَلَ بِقَنَاةَ فَاسْتَتْبَعَنِي إِلَيْهِ عَبْدُ اللَّهِ بْنُ عُمَرَ يَعُودُهُ فَانْطَلَقْتُ مَعَهُ فَلَمَّا جَلَسْنَا سَأَلْتُ ابْنَ مَسْعُودٍ عَنْ هَذَا الْحَدِيثِ فَحَدَّثَنِيهِ كَمَا حَدَّثْتُهُ ابْنَ عُمَرَ قَالَ صَالِحٌ وَقَدْ تُحُدِّثَ بِنَحْوِ ذَلِكَ عَنْ أَبِي رَافِعٍ  

[Machine] the Messenger of Allah ﷺ said, 'There has not been a prophet except that he had disciples whom he would guide with his guidance and who would follow his Sunnah (way of life). Then after them, there would be generations who would say what they do not do and do what they disapprove of. So, whoever fights against them with his hands, he is a believer, and whoever fights against them with his tongue, he is a believer, and whoever fights against them with his heart, he is a believer. There is no faith beyond that even to the weight of a mustard seed.'  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَا كَانَ مِنْ نَبِيٍّ إِلَّا كَانَ لَهُ حَوَارِيُّونَ يُهْدُونَ بِهَدْيِهِ وَيَسْتَنُّونَ بِسُنَّتِهِ ثُمَّ يَكُونُ مِنْ بَعْدِهِمْ أَقْوَامٌ يَقُولُونَ مَا لَا يَفْعَلُونَ وَيَفْعَلُونَ مَا يُنْكِرُونَ فَمَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِلِسَانِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِقَلْبِهِ فَهُوَ مُؤْمِنٌ لَيْسَ وَرَاءَ ذَلِكَ مِنَ الْإِيمَانِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ»  

[Machine] Narrated by Abu Rafi, the freed slave of the Messenger of Allah, from Abdullah bin Mas'ud, who said that the Prophet of Allah, ﷺ , said: "There was no prophet who did not have disciples who followed his guidance and followed his Sunnah (traditions). Then there will come after them successors who say what they do not do, and do what you disapprove of. Whoever fights against them with his hand is a believer, and whoever fights against them with his tongue is a believer, and whoever fights against them with his heart is a believer. There is no faith beyond that, even if it were as small as a mustard seed."  

عَنْ أَبِي رَافِعٍ مَوْلَى رَسُولِ اللهِ ﷺ عَنْ عَبْدِ اللهِ بْنِ مَسْعُودٍ أَنَّ نَبِيَّ اللهِ ﷺ قَالَ «مَا كَانَ مِنْ نَبِيٍّ إِلَّا كَانَ لَهُ حَوَارِيُّونَ يَهْدُونَ بِهَدْيِهِ وَيَسْتَنُّونَ سُنَّتَهُ ثُمَّ يَكُونُ مِنْ بَعْدِهِمْ خُلُوفٌ يَقُولُونَ مَا لَا يَفْعَلُونَ وَيَعْمَلُونَ مَا تُنْكِرُونَ مَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِلِسَانِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِقَلْبِهِ فَهُوَ مُؤْمِنٌ لَيْسَ وَرَاءَ ذَلِكَ مِنَ الْإِيمَانِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ»  

"مَا مِنْ نَبِيٍّ بَعَثَهُ الله في أُمَّةٍ قَبْلى، إِلا كان له من أُمَّتِهِ حوَارِيُّون وَأَصْحَابٌ يأخذونَ بسنَّتِهِ ويقتدونَ بأَمره، ثم إِنَّها تَخْلُفُ من بعدِهم خُلُوفٌ يَقُولون ما لا يفعلون، ويفعلون ما لا يُؤْمرون، فمن جاهدهم بيده فهو مُؤْمن، ومن جاهدهم بلسانه فهو مؤْمنٌ، ومن جَاهَدَهُم بِقلْبِه فهو مُؤْمِنٌ، ليسَ وَرَاءَ ذلك من الإِيمان حَبَّةُ خَرْدَلٍ".
