Is it possible to marry a girl who previously sent nude pictures of herself, knowing that it was wrong, and how can the matter be forgotten?

The relationship between a man and a woman in Islam is defined by Sharia regulations, and the acts of embracing and touching that occurred are forbidden. The girl must repent for her past sin, conceal herself, and delete the explicit pictures. If you see genuine repentance from her and her situation becomes upright, then there is no blame upon you in marrying her, for the Prophet, peace and blessings be upon him, said: "And whoever conceals a Muslim, Allah will conceal him in this world and the Hereafter." However, the pictures must be deleted permanently. If you know that you will not be able to overcome the matter, then we do not advise you to marry her.
