What is the ruling on eating two chickens that were slaughtered twice, with a time difference of approximately one hour, given that their souls did not depart from the first slaughter?

If the slaughterer severs the vital organs of the animal in the first cut without completing the slaughter, and then completes it in a second cut, the slaughtered animal is not permissible to eat. So, if one lifts their hand before completing the slaughter and then returns to it, the animal becomes impermissible to eat if there is a long interval, whether the lifting was intentional or due to necessity. However, if the slaughter was definitively completed in the first instance, then there is no harm in repeating the slaughter.
