Tahqiq -manat (establishment of the effective cause) is thought to
be the core of religious Ijtihad(independent scholarly reasoning) and
one of the fundamental principles for applying the rules and
extending them to secondary related issues and incident , This
research is meant to highlight the importance of establishing the
effective cause in unprecedented matters and incidents through
elucidating the concept along with the definition of nawazil
(unprecedented incidents), in addition to shedding light on the
different degrees and restrictions of verifying the effective cause. The
research dedicated a practical study to the newly-occurred issue of
slaughtering by means of modern electrical machines where the
question is tackled with regard to the views of religious jurists and in
accordance with the way of establishing the effective cause in terms
of the slaughtering method. In conclusion, the study revealed that the
use of such tools is permitted whenever the conditions of the
slaughtered animal’s permissibility are gathered.
