A man abandoned hashish and said: “It is forbidden to me as my mother is.” If he returns to it, is he required to pay the expiation for an oath or the expiation for zihar?

Question:
Honorable Shaykh, may Allah grant you success. He says: A man was using hashish, then he abandoned it and said, “It is forbidden to me, meaning the hashish, it is forbidden to me as my mother is.” He asks: Does this require the expiation for an oath or the expiation for zihar? He used the hashish, he utilized the hashish, and then he used the hashish after that.

Answer:
He is required to pay the expiation for an oath, along with repentance to Allah and abandoning the hashish. He expiates for his oath and leaves it. However, if he did not return to the hashish and continued to abstain from it, praise be to Allah, and nothing is required of him. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions.
