Committing sex with animals is forbidden. A person who commits this (Part No. 22; Page No. 73) must repent to Allah, seek His forgiveness, give up this act, regret the past sins and make up his mind not to repeat this again. If he was caught during the crime, the Muslim ruler should punish him with the proper punishment which will deter him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
