Bukhari 6878:Killing Allowed In Three Instances (Fornication, Murder & Apostasy)
Thank you for the answer. From this explanation what I understand is that this Hadith is a guideline for the time of Prophet Muhammad (peace be upon him). الثَّيِّبُ الزَّانِي: No more applicable because the itmam-e-hujjat was done at that time but not possible afterwards. وَالتَّارِكُ لِدِينِهِ الْمُفَارِقُ لِلْجَمَاعَةِ: same as above. وَالنَّفْسُ بِالنَّفْسِ: still applies because it is a crime according to Quran. Is my understanding correct?
