Hadith #2116480

Abu Dawud narrated a similar hadith that reads, "The slaughtering (of an animal) by any Muslim is Halal (lawful) whether or not he mentioned Allah's name over it." Its narrators are reliable.

وَلَهُ شَاهِدٌ عِنْدَ أَبِي دَاوُدَ فِي "مَرَاسِيلِهِ" بِلَفْظِ: { "ذَبِيحَةُ اَلْمُسْلِمِ حَلَالٌ, ذَكَرَ اِسْمَ اَللَّهِ عَلَيْهَا أَوْ لَمْ يَذْكُرْ" } وَرِجَالُهُ مُوَثَّقُونَ (1761)‏ .‏
