When Islam classifies something as a SIN, it is firstly because it is a thing that Allah dislikes; secondly it is due to outweighing harm from the sin on this life (with respect to purpose of life); and thus thirdly, due to 1st and 2nd reasons, the sin makes the sinner who was disobedient of Allah, punishable in this life or/and in the Aakhirah (the Next-life) in Hellfire. Imam Dhahabi authored, 'The Book about the Major Sins,' listing the 70 Major Sins considered the worst sins according to Islam, along with mention of few verses and/or hadith about each of those major sins. Here is a list of the 70 Major Sins listed in the original Arabic and English translation.
