Believe only in Allah, Respect life & Marriage Vows/Privacy/Trust between spouses

This hadith from Abdullah ibn Mas'ud explains the three greatest sins in the eyes of Allah. The first and most serious sin is to associate partners with Allah, which means to believe that there are other gods besides Him or to give something else equal status as God. This is considered a grave offense because it goes against His commandment that He alone should be worshipped. The second greatest sin is killing one's own child out of fear that they will consume food; this act goes against the natural bond between parent and child and shows a lack of faith in God’s ability to provide for them. Lastly, committing adultery with someone else’s spouse is considered a great sin because it violates another person’s right to privacy and trust within their marriage. All three sins are serious offenses in Islam and should be avoided at all costs.
