صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 6274
Asking Permission
Whoever sat in a relining posture
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرٌ، مِثْلَهُ، وَكَانَ مُتَّكِئًا فَجَلَسَ فَقَالَ أَلاَ وَقَوْلُ الزُّورِ . فَمَا زَالَ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ.
Narrated Bishr: as above (No. 290) adding: The Prophet (ﷺ) was reclining (leaning) and then he sat up saying, "And I warn you against giving a false statement." And he kept on saying that warning so much so that we said, "Would that he had stopped."
