Mishkat al-Masabih 2 Knowledge كتاب العلم 31

وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ قَالَ فِي الْقُرْآنِ بِرَأْيِهِ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ» . وَفِي رِوَايَةٍ: «مَنْ قَالَ فِي الْقُرْآنِ بِغَيْرِ عِلْمٍ فَليَتَبَوَّأ مَقْعَده من النَّار» رَوَاهُ التِّرْمِذِيّ

Ibn ‘Abbas reported God’s messenger as saying, “Let him who interprets the Qur’an in the light of his opinion come to his abode in hell.” A version has, “Let him who interprets the Qur’an without knowledge come to his abode in hell.” Tirmidhi transmitted it.
