Is it obligatory for the slaughterer to invoke the name of Allah over the animal being slaughtered, or is it sufficient for the one present to invoke it?

The questioner : Shaykh Muhammad, this questioner says in her first question: If, when slaughtering the animal, the second person present invokes the name of Allah over the animal, but the slaughterer does not, is that permissible?

The Shaykh : This is not permissible. It is obligatory for the slaughterer himself to invoke the name of Allah.

The questioner : And his soul.

The Shaykh : When intending to slaughter. If the one present invokes the name of Allah and the slaughterer does not, the animal is forbidden (haram) and it is not permissible to eat it. This is based on the saying of Allah, Blessed and Exalted is He: and the saying of the Prophet (peace and blessings be upon him): "Whatever flows its blood and the name of Allah is mentioned over it, eat it." And his saying (peace and blessings be upon him): "If you send your arrow and mention the name of Allah over it, eat it." Therefore, the invocation is necessary, and it must be by the slaughterer at the time of intending to slaughter.

The questioner : If he was forgetful, O Shaykh.

The Shaykh : If he was forgetful, the animal is not lawful due to the generality of the saying of Allah the Exalted: and because mentioning the name of Allah is one of the conditions, and conditions are not dropped due to forgetfulness.
