Taking the statements of a specific man placing them on the level of the text of the Legislator to where the statements of others are not looked at, rather, the text of the Legislator (is not looked at), except when it agrees with his statement?
اتِّخَاذِ أَقْوَالِ رَجُلٍ بِعَيْنِهِ بِمَنْزِلَةِ نُصُوصِ الشَّارِعِ لَا يُلْتَفَتُ إلَى قَوْلِ مَنْ سِوَاهُ بَلْ وَلَا إلَى نُصُوصِ الشَّارِعِ إلَّا إذَا وَافَقَتْ نُصُوصَ قَوْلِهِ؟،
By Allah, this is what the ummah has united upon being ḥarām in the religion of Allah.
فَهَذَا وَاَللَّهِ هُوَ الَّذِي أَجْمَعَتْ الْأُمَّةُ عَلَى أَنَّهُ مُحَرَّمٌ فِي دِينِ اللَّهِ،
This has not appeared amongst the ummah except after the passing of the virtuous generations.
وَلَمْ يَظْهَرْ فِي الْأُمَّةِ إلَّا بَعْدَ انْقِرَاضِ الْقُرُونِ الْفَاضِلَةِ.
Ibn al-Qayyim, Iʿlām al-Muwaqqʿīn ʿan Rabb al-ʿĀlamīn 2/166
