Q: A Muslim sister from 'Unayzah in the Kingdom of Saudi Arabia poses the following question, "During my past studying years, we had in our school a library which includes a large number of books and magazines which were of no interest for the students. I love reading and keeping books. I liked the religious, medical and narrative books in our library and borrowed about four books to read them and then to give them back. However, due to being engaged in studying, I forgot to give them back to the library. Three years after graduating from the school, a friend told me that it is Haram (prohibited) to keep these book with me and that I should give them back to the library and that I am to be accounted for this on the Day of Resurrection. You should bear in mind that I was ignorant of this ruling when I borrowed them. Moreover, the library was of no interest for the teachers or students. Besides, I benefit from these books much, particularly the religious ones, and I do not want to give them back." What is the ruling? May Allah reward you well.
