The fatwa, an Islamic edict, was widely attributed to the mufti of Saudi Arabia, Abdul Aziz bin Abdullah.
The grand mufti, who is the highest religious figure in Saudi Arabia, allegedly went on to substantiate the fatwa by saying this will allow the couple to "become one as their bodies will fuse together after the husband eats his wife".
According to multiple local reports, the fatwa "allows a man to eat his wife or parts of her body, if the husband was afflicted with a severe hunger".
The report added: "The fatwa is interpreted as evidence of the sacrifice of women and obedience to her husband and her desire for the two to become one."
The alleged fatwa has stoked controversy as many derided it over various social media platforms.
