The authenticity of the hadith: "There is no major sin with seeking forgiveness, and no minor sin with persistence"

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the authenticity of this hadith: "There is no major sin with seeking forgiveness, and no minor sin with persistence," and what is its meaning?

Answer:
Yes, its meaning is correct. There is no major sin with seeking forgiveness. Whoever seeks forgiveness from Allah sincerely, Allah forgives him and accepts his repentance, even if his sins were such, even if he were a great sinner. If he repents, Allah accepts his repentance. Say to those who have committed great sins: "We will inform them of what has grieved them. If they repent and establish prayer and give zakah, they are your brothers in religion."
So there is no major sin with seeking forgiveness and repentance. Allah erases sins through repentance. Repentance wipes out what came before it. Likewise, there is no minor sin with persistence. If a person is lax about a minor sin, continues with it, and persists in it, it becomes a major sin. It transforms into a major sin because he no longer cares and does not fear Allah the Exalted. He persists in the disobedience, and it becomes a major sin by these considerations. Its origin is a minor sin, but the persistence, the continuity, and the lack of shame before Allah are what made it a major sin.
