from Abu Rafi' and others, from the Prophet ﷺ who said: "Let me not find one of you reclining on his couch when a command I ordered, or a prohibition from me comes to him, and he says: 'I do not know. What we find in the Book of Allah, we follow it.'"  

لاَ أُلْفِيَنَّ أَحَدَكُمْ مُتَّكِئًا عَلَى أَرِيكَتِهِ يَأْتِيهِ أَمْرٌ مِمَّا أَمَرْتُ بِهِ أَوْ نَهَيْتُ عَنْهُ فَيَقُولُ لاَ أَدْرِي مَا وَجَدْنَا فِي كِتَابِ اللَّهِ اتَّبَعْنَاهُ  

that the Messenger of Allah ﷺ said: "Lo! Soon a Hadith from me will be conveyed to a man, while he is reclining on his couch, and he says: 'Between us and you is Allah's Book. So whatever we find in it that is lawful, we consider lawful, and whatever we find in it that is unlawful, we consider it unlawful.' Indeed whatever the Messenger of Allah ﷺ made unlawful, it is the same as what Allah made unlawful."  

قَالَ رَسُولُ اللَّهِ ﷺ أَلاَ هَلْ عَسَى رَجُلٌ يَبْلُغُهُ الْحَدِيثُ عَنِّي وَهُوَ مُتَّكِئٌ عَلَى أَرِيكَتِهِ فَيَقُولُ بَيْنَنَا وَبَيْنَكُمْ كِتَابُ اللَّهِ فَمَا وَجَدْنَا فِيهِ حَلاَلاً اسْتَحْلَلْنَاهُ وَمَا وَجَدْنَا فِيهِ حَرَامًا حَرَّمْنَاهُ وَإِنَّ مَا حَرَّمَ رَسُولُ اللَّهِ ﷺ كَمَا حَرَّمَ اللَّهُ
