Abdullah bin Masud reported,

I asked, or the Messenger of Allah ﷺ was asked, "Which sin is greatest in the sight of Allah?"He replied, "That you set up a rival to Allah, though it is He who created you."I asked, "And then which?"He said, "That you kill your own child for fear that he will eat along with you."I asked, "And then which?"He said, "That you commit adultery with your neighbor's wife."The narrator said that this verse was then revealed, confirming what the Messenger of Allah ﷺ had said, "And those who do not call upon another god besides Allah, nor kill the soul which Allah has forbidden except by right, nor commit adultery" [Furqan 25:68].

His saying, "And those who do not invoke with Allah another deity, nor kill the soul which Allah has forbidden except by right, nor commit unlawful sexual intercourse. And whoever does that will meet a penalty. Multiplied for him is the punishment on the Day of Resurrection, and he will abide therein humiliated. Except for those who repent, believe, and do righteous work, for them Allah will replace their evil deeds with good. And Allah is Forgiving, Merciful"
