A modernist deviate in Sri Lanka is propagating that the meat will be halaal even if a kaafir recites Tasmiyah when he slaughters the animal.

Answer

The animal slaughtered by a kaafir will be haraam carrion even if the kaafir recites Tasmiyah a thousand times. The Tasmiyah of the kaafir is not valid. The validity of the Tasmiyah depends on Imaan. The person appears to be extremely ignorant hence he claimed that the Tasmiyah of a kaafir is valid.

The argument that the Qur'aan does not mention the faith of the slaughterer is absolutely corrupt and it portrays the gross ignorance of the person. Thousands of detailed masaa-il are not mentioned in the Qur'aan. The Qur'aan does not mention that there are five Fardh Salaat daily nor does the Qur'aan mention the number of raka'ts in every Salaat, nor does it mention the amount of Zakaat to be paid. In fact, the greater part of Islam's rules and regulations are not mentioned in the Qur'aan. It does not follow from this that five Salaat are not Fardh, and that the 2 raka'ts of Fajr, 4 raka'ts of Zuhr, four of Asr, 3 of Maghrib and 4 of Isha' are not compulsory.

Brother, it is best not to discuss with such an ignorant person. The more you will discuss with him, the more stubborn and stupid will he become.
