Kinship through breastfeeding

The questioner:
In the second question, Shaykh, there is a girl who has paternal uncles through breastfeeding, and she has never visited them, nor have they visited her, but...

The Shaykh:
What? A girl. Yes.

The questioner:
She has blind uncles through breastfeeding.

The Shaykh:
Her uncles through breastfeeding.

The questioner:
Yes, and she has never visited them, nor have they visited her, or even spoken to them; she does not know them. Is she sinful in this matter? And is this severing of kinship ties?

The Shaykh:
No, they are not kin; breastfeeding is not kinship, and they do not have the rights of maintaining kinship ties. However, they have the rights of Muslims, like all other Muslims. As for kinship, it is specific to blood relations. These people are not blood relatives. Yes.
