Does animal/bird hear the Shahada or Tasmiya recited by the slaugherman/men at slaughtering station?
A. Books of Fatawas, does not make it mandatory. One should be mindful that the decibels in modern plant are so high that at times even the slaughterman has to wear the earplugs. Ni’at or intention of slaughterer to slaughter in the name of Allah is compulsory and necessary – after all we are borrowing one from His flocks for our sustaining, consumption & nourishment. Allah says in Qur’an: Al-Anam 6-118 Al-Anam 6- 1st Part of 119 Al-Anam 6_ 1st part of 121 May Allah give us hidayat to seek, procure and consume halal always – Insha Allah.
