Will a girl be held accountable if she chooses to marry a non-Black person out of fear for her children from the racism she experienced, and is this way of thinking considered forbidden in Islamic law, and is it possible for Allah to bless her with Black children even if she marries a white man because of this thinking, and is this type of thinking forbidden in Islamic law, and how can one repent from it if it is forbidden?

There is no sin upon a woman for refusing to marry a dark-skinned man, as this is her right to choose. It is permissible for her to choose whomever she finds pleasing in appearance or acceptable to herself, even if the reason is worldly. Islamic law does not oblige her to marry someone she does not accept, whether she considers herself or her future children.

What is forbidden is arrogance or despising a Muslim brother due to color or race: "It is enough evil for a man to despise his Muslim brother."

This is based on two points: 1. Unwillingness to marry a dark-skinned man to prevent harm is not considered injustice or arrogance. 2. Islamic law has given women the right to choose their husband and has forbidden compelling them, and there is no sin in her choosing a specific characteristic in a husband.

It is recommended to focus on the man's religiosity and character, for with good religion and character, the marital relationship will be complete.
