Before slaughtering an animal like a cow, sheep, goat, camel, buffalo, or ram in accordance with Islamic Shariah, it is obligatory for Muslims to recite a dua or prayer to seek the blessing and guidance of Allah.
This prayer is a way to express gratitude for the sustenance provided by the animal and to ensure that the act of slaughter is performed in a humane and respectful manner.
This dua was reported in an authentic hadith of the Prophet in Sahih Muslim reference in Hisn al-Muslim.
Below is the Dua before slaughtering cow, sheep, goat, camel, buffalo, and ram in Arabic, English translation and transliteration.
بِسْمِ اللَّهِ وَاللَّهُ أَكْبَرُ اللَّهُمَّ مِنْكَ ولَكَ اللَّهُمَّ تَقَبَّلْ مِنِّيArabic
Bismillaahi wallaahu ‘Akbar [Allaahumma minka wa laka] Allaahumma taqabbal minnee.Transliteration
With the Name of Allah, Allah is the Most Great! (O Allah, from You and to You.) O Allah, accept it from me.Translation
