Allah is my witness to what I say, I only used the books for two months and then put them in the drawer, and they are of no use to me. I studied from them and finished, praise be to Allah. The books are truly useful for those who want to study from them, have abilities, and want to raise their grades. I bought them and hired a tutor to study with me from them, and now they are of no use to me, so I am offering them for sale. I have finished studying, praise be to Allah, and I want to sell them.
