Abdullah bin Masud reported,

I asked the Prophet ﷺ, "Which sin is greatest in the sight of Allah?"He replied, "That you set up a rival to Allah, when He created you."I said, "That is indeed grave. Then which?"He said, "That you kill your child out of fear that he will eat with you."I asked, "Then which?"He said, "That you commit adultery with your neighbor's wife."

سألت النبي ﷺ: أي الذنب أعظم عند الله؟ قال: أن تجعل لله ندا وهو خلقك قلت: إن ذلك لعظيم، قلت: ثم أي؟ قال: وأن تقتل ولدك تخاف أن يطعم معك قلت: ثم أي؟ قال: أن تزاني حليلة جارك.
