The need to recite Bismillah during Qurbani 3551549927

If there is more than one slaughterer, each one has to say Bismillah separately. Therefore, in the case in question, if Imam Sahib does not complete the slaughter and gives it to the butcher or someone else, the second person should also say Bismillah. In this case, if the second person does not say Bismillah intentionally, the slaughter will not be valid and the meat of this animal cannot be eaten. Sacrifice will not be valid. Of course, if the first person finishes the basic part of the slaughter (i.e. cuts one of the esophagus, trachea and esophagus), then it is not necessary to say Bismillah if someone else stabs him, but it is better to say. 6162447282
