The Shaykh:
It is not permissible to delay repentance. He said, "If in the future such and such happens, I will repent." It is not permissible to delay repentance to Allah. One should hasten to repent and not delay it. Yes, to complete what was mentioned before: if you delay repentance, do you have a guarantee that you will remain alive until the time you say you will repent? You may die before that while still in sin, so hasten to repent. Yes, repeat the question.

The questioner:
He says: A man vowed to quit smoking if Allah blessed him.

The Shaykh:
We are done with this. We said: do not delay repentance; hasten to it. Yes.
