Muslim women can greet other women like men greet other men. Greetings between women is more affectionate and can involve hugs. If you are a close friend with the female Muslim, you can exchange three kisses on each cheek. But some women may be less physically affectionate in a public place or if they are in the view of men who do not belong to their family. It is also appropriate if you do not know the female Muslim well to greet her verbally with a respectful nod and a smile if you feel that she is not keen to be touched.
