Shall I inform you of the gravest of the major sins?

Explanation

The Prophet (may Allah's peace and blessings be upon him) informed his Companions about the gravest of the major sins and mentioned these three: 1. Associating partners with Allah: This is to devote any form of worship to other than Allah and regard anyone as equal to Allah in His divinity, lordship, names, and attributes. 2. Undutifulness to parents: This is any hurt to one's parents, whether by word or deed, and not showing kindness to them. 3. False statement, which includes perjury: Every false and untrue statement intended to detract from the one about whom it is made by taking his property, damaging his honor, and the like. The Prophet (may Allah's peace and blessings be upon him) repeated the warning about the false testimony to highlight its hideousness and evil consequences for society, so much that the Companions wished that he would be quiet out of compassion towards him and disliking what would annoy him.

Benefits

• The gravest sin is associating partners with Allah, as he puts it at the forefront of the major sins and the greatest one among them. This is confirmed by the verse: {Allah does not forgive associating partners with Him, but forgives anything less than that for whom He wills. Whoever associates partners with Allah has indeed committed a grave sin.}
• The rights of parents are significant, as he coupled them with the rights of Allah Almighty.
• Sins are divided into major and minor. Major sins are every sin that entails a worldly penalty, like the prescribed punishments and curses, or a threat regarding the Hereafter, such as the threat of entering Hellfire. There are different levels of major sins, some of which are more severe than others in terms of prohibition. Minor sins are the sins other than the major ones.
