The ruling on greeting a maternal uncle through breastfeeding and uncovering before him

Question:
Honorable Shaykh, my wife discovered that she has a maternal uncle through breastfeeding. This uncle has greeted all her sisters through breastfeeding, but my wife was overcome with shyness, so she has not greeted him to this day, now that we have confirmed that he is her maternal uncle through breastfeeding. Do you command her to greet him and uncover before him? And is there a sin in not greeting him and not uncovering before him?

Answer:
This is not a blood relative. Breastfeeding is not a blood relative, and he is not a close relative. It is not obligatory for her to uncover before him and greet him. As long as shyness prevents her, there is no harm in her refraining. If the shyness goes away later, she should greet him. If it does not go away, it is not obligatory for her to greet him, and it is not obligatory for him to greet her. There is no severing of family ties in this, because this is not kinship. Rather, this is a permissible matter. It is permissible for him to greet her and for her to greet him, and she is not required to veil herself from him. If she is overcome with shyness, she is not forced to greet him and for him to greet her. This is something that is not obligatory. Yes.
