What are the seven major sins mentioned in the noble Hadith: "There is no servant who prays the five prayers, pays Zakat, fasts Ramadan, performs Hajj to the House, and avoids the seven major sins, except that it will be said to him on the Day of Resurrection: 'Enter Paradise in peace'"?

The seven grave sins are the seven destructive sins mentioned in the authentic hadith in the Two Sahihs: associating partners with Allah (shirk), sorcery, killing a soul which Allah has forbidden except by right, consuming Riba (usury), consuming the property of an orphan, fleeing on the day of the march (battle), and slandering chaste, innocent, believing women. Avoiding these grave sins, along with observing the five daily prayers, fasting Ramadan, and paying Zakat, opens the doors of Paradise for a Muslim.
