FOLLOW THE WAY OF THE PROPHET, praise and peace be upon him H 186 "Each Prophet sent before me had devoted disciples and Companions who would follow his practice and obey his orders. Then, these were followed by those who said that which they did not do, and did that which they were not ordered. Whosoever fights them with his hands is a believer, as is he who fights them with his tongue, also he who fights them in his heart. After this there is not as much as a grain of faith left." R 186 Muslim with a chain up to ibn Mas'ud who related that the Prophet, praise and peace be upon him, said this.
185- الثاني : عن ابن مسعود رضي الله عنه : أن رَسُول الله صلى الله عليه وآله وسلم ، قَالَ : "مَا مِنْ نَبيٍّ بَعَثَهُ اللهُ في أمَّة قَبْلِي إلاَّ كَانَ لَهُ مِنْ أُمَّتِهِ حَوَارِيُّونَ وَأصْحَابٌ يَأخُذُونَ بِسنَّتِهِ وَيَقْتَدُونَ بِأَمْرِهِ ، ثُمَّ إِنَّهَا تَخْلُفُ مِنْ بَعْدِهِمْ خُلُوفٌ يَقُولُونَ مَا لاَ يَفْعَلُونَ وَيَفْعَلُونَ مَا لا يُؤْمَرونَ ، فَمَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ ، وَمَنْ جَاهَدَهُمْ بِقَلبِهِ فَهُوَ مُؤمِنٌ ، وَمَنْ جَاهَدَهُمْ بِلسَانِهِ فَهُوَ مُؤمِنٌ ، وَلَيسَ وَرَاءَ ذلِكَ مِنَ الإيمَانِ حَبَّةُ خَرْدَل" رواه مسلم .
