[تحريم البدع :] وَاعْلَمُوا عِبَادَ اللهِ أَنَّ الْمُؤمِنَ يَسْتَحِلُّ الْعَامَ مَا اسْتَحَلَّ عَاماً أَوَّلَ، وَيُحَرِّمُ الْعَامَ مَا حَرَّمَ عَاماً أَوَّلَ، وَأَنَّ مَا أَحْدَثَ النَّاسُ لاَ يُحِلُّ لَكُمْ شَيْئاً مِمَّا حُرِّمَ عَلَيْكُمْ، وَلكِنَّ الْحَلاَلَ مَا أَحَلَّ اللهُ، وَالْحَرَامَ مَا حَرَّمَ اللهُ، فَقَدْ جَرَّبْتُمُ الاْمْورَ وَضَرَّسْتُمُوهَا، وَوُعِظْتُمْ بِمَنْ كَانَ قَبْلَكُمْ، وَضُرِبَتِ الاْمْثَالُ لَكُم، وَدُعِيتُمْ إلَى الاْمْرِ الْوَاضِحِ; فَلاَ يَصَمُّ عَنْ ذلِكَ إلاَّ أَصَمُّ، وَلاَ يَعْمَى عَنْهُ إلاَّ أَعْمَى.
[Following the sunnah and refraining from innovation :] Know, O creatures of Allāh, that a believer should regard lawful this year what he regarded lawful in the previous year, and should consider unlawful this year what he considered unlawful in the previous year. Certainly people’s innovation cannot make lawful for you what has been declared unlawful; rather, lawful is that which Allāh has made lawful and unlawful is that which Allāh has made unlawful. You have already tested the matters and tried them; you have been preached by those before you. Illustrations have been drawn for you and you have been called to clear fact. Only a deaf man can remain deaf to all this, and only a blind man can remain blind to all this.
