Cutting off the voluntary prayer when the call to prayer is made

Question:
The questioner: May Allah reward you. We said in the previous lesson that if the prayer begins, the author cuts off his prayer in the greater tasbih. How is that possible, and this voluntary prayer has become invalid in the standing of the prayer? And his saying (peace and blessings be upon him): "If the prayer begins, there is no prayer to be completed." And if it has already started, how do I record it?

Answer:
I said it is better. I tell him to say the taslim and he may leave without the taslim. That is what I said. I did not say that saying the taslim is better.
As for the opinion of the one who generalizes the saying of the Prophet (peace and blessings be upon him), "Its opening is the takbir and its closing is the taslim," he generalizes this, and the beginning of the prayer is not invalid, and there is a reward in it. As for the one who says that the beginning of his prayer is invalid, he is boycotted in it, except if he entered the voluntary prayer after the iqamah. If he entered the voluntary prayer while the imam is calling the iqamah, it is invalid without doubt, and he has no reward in it, as he is contrary to the prohibition. But if he entered it before the iqamah, and then the prayer was called while he was in the middle of it, the beginning of his prayer is valid and he is rewarded for it. But the scholars differed on whether he should continue and complete it or cut it off; this is the point of disagreement. And if he cuts it off, the beginning of it does not count for him in terms of reward. Yes.
