[Machine] The Messenger of Allah ﷺ said: "Whoever attributes to me what I have not said, let him take his seat in the Fire. And whoever consults his brother and he guides him without proper knowledge, then he has betrayed him. And whoever issues a fatwa without it being firmly established, then his sin is upon the one who asked his opinion." This is the saying of Ibn Wahb.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ قَالَ عَلَيَّ مَا لَمْ أَقُلْ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ وَمَنِ اسْتَشَارَهُ أَخُوهُ فَأَشَارَ عَلَيْهِ بِغَيْرِ رُشْدِهِ فَقَدْ خَانَهُ وَمَنْ أَفْتَى بِفُتْيَا غَيْرِ ثَبْتٍ فَإِنَّمَا إِثْمُهُ عَلَى مَنْ أَفْتَاهُ لَفْظُ حَدِيثِ ابْنِ وَهْبٍ
