The fatwa, an Islamic edict, was widely attributed to the mufti of Saudi Arabia, Abdul Aziz bin Abdullah though it is yet to be officially confirmed.
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. However, there has been no mention of such fatwa listed on the mufti's website as yet.
Nonetheless, religious authorities quickly denied that Saudi mufti issued any such fatwa to quell the speculation.
"The truth is that this is fabricated and made up from its basis. These ill thoughts cannot come from any Muslim, regardless of a great scholar who Muslims refer to from around the world," he added. It was made up to create this confusion and damage," Khalid ben Abdel-Rahman El-Shaye', assistant secretary general of the Global Commission for Introducing the Messenger, affiliating to the Muslim World League, told CNN Arabic.
