What is the ruling on using a sex doll with the intention of releasing sexual urges and avoiding zina (unlawful sexual intercourse) when one is unable to marry, and what is advised for those who do so?

The prohibition of this act has been previously explained. It is incumbent upon the one who commits it to strive against their self (nafs), to distance themselves from lust-provoking stimuli, and to engage in their antidotes. Masturbation due to necessity has a special ruling. It is impermissible for him to keep the doll because it is a forbidden image and a cause for arousing lust. And whoever is afflicted with a sin, let him conceal it and not publicize it, for publicizing it is another sin.
