A man giving Islamic tapes to a non-mahram woman
Question

                I have a female neighbour whose husband is travelling. She prays and obeys the commands of Allaah, but sometimes she appears in front of me and speaks to me about religious matters, and asks me to buy religious tapes for her. If I give her some religious tapes, what is your opinion on that?.
Praise be to Allah.There is nothing wrong with you giving some 
    Islamic tapes that are beneficial and free of anything that is forbidden according to sharee’ah to this non-mahram woman. But you have to try to 
    give the tapes to her via some of your female mahrams. That will be safer for your religious commitment and further removed from areas of doubt, 
    suspicion and temptation. 
And Allaah is the Source of strength.

It is not permissible for her to appear in 
    front of you without full hijab, and it is not permissible for her to be alone with you.
