Why is the entry of all Muslims into Paradise, both the pious and the dissolute, considered one of the fundamental tenets of the doctrine of Ahl al-Sunnah wa al-Jama'ah, despite the absence of a definitive, unequivocally proven and interpreted text confirming this, and how is the contradiction of this principle with the verses and hadiths that speak of eternal damnation in Hell for some Muslims who commit grave sins explained?

The People of Sunnah and Community (Ahlus-Sunnah wal-Jama'ah) believe that perpetrators of major sins among monotheists are subject to the will of Allah; if He wills, He will punish them, and if He wills, He will forgive them. They base this on Allah's saying: "Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills." [An-Nisa: 48].

And if He punishes them in Hellfire, their ultimate destiny is to exit it, relying on the hadiths of the Prophet, peace and blessings be upon him, such as: "A visitor from my Lord came to me and gave me the glad tidings that whoever from my nation dies without associating anything with Allah will enter Paradise," and "Take out from the Fire whoever has in their heart the weight of a mustard seed of faith."

The People of Sunnah believe that the textual evidences indicating the eternal dwelling of perpetrators of major sins in Hellfire must be reconciled and harmonized, not contradicted against each other.
