What is the meaning of min in "from (min) your sins"?

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. It is superfluous (hence it means: "and it will atone for your bad deeds.")
2. It has the partitive meaning ( hence "some of your bad deeds").
