What is the ruling on greeting the daughter of one's paternal uncle and the daughter of one's maternal uncle?

Question:
Is it permissible for me to greet a female relative, such as the daughter of my maternal uncle or the daughter of my paternal uncle, who is twenty years older than me? Please note that she is married and used to show me kindness when I was young, in the place of a mother, because my mother passed away and my father was with me when I was three years old. Please advise us, may Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. To proceed: There is no harm in greeting your paternal aunt or your maternal aunt, or any of your female relatives, or any Muslim woman, even if she is not a relative. The mere greeting with words only, without shaking hands, without shaking hands with a woman, is permissible if there is no fear of fitnah (trial, discord or temptation) arising from it, provided it is just a greeting. This is especially so if this woman is one of your relatives, or if she has a favor upon you, as you mentioned regarding her good upbringing of you and her care for your interests when you were young. So, being dutiful to her and doing good to her includes maintaining ties with her through greeting and other means; because there is benefit in this, and no harm, and it is a return of the favor. So, there is no harm in greeting her without shaking hands, asking about her condition, and making du'a' (supplication) for her.
