The ruling on interrupting the prayer after beginning it in order to delay it

The questioner:
A man prayed the 'Isha' prayer, and he remembered that the time was long, so he had a state of ritual impurity and interrupted his prayer, then he performed wudu' (ablution) and said, "I want to pray later before the time ends." It is well known that it is not permissible to interrupt an obligatory act, such as a prayer, fast, Hajj, or other, once one has begun it. What is the ruling regarding this person's action?

The Shaykh:
What is he saying?

The questioner:
A man prayed the 'Isha' prayer, and he remembered that the time was near, so he had a state of ritual impurity and interrupted his prayer, then he performed wudu' (ablution) and said, "I want to pray later before the time ends."

The Shaykh:
This is a mistake, this is a mistake. It is not permissible, once one has begun the prayer, to interrupt it except for a necessary excuse. It is not permissible to interrupt the prayer and say, "The time is wide, I will interrupt the prayer and pray later." This is haram (forbidden) and not permissible. Allah the Exalted said: It is not permissible to interrupt the prayer in such a situation. This is an error, and he must repent from this matter and not return to it. Yes.

The questioner:
It is authentic from Shiddah.

The Shaykh:
He did it intentionally. He intentionally had a state of ritual impurity when he saw that he was saying the time was long, wanting to interrupt it and break his wudu' (ablution). However, if the state of ritual impurity occurred without his choice, there is no sin on him and the prayer is valid in it, but he intentionally did this thing based on the fact that the time is wide, he says.

The questioner:
The Shaykh's position.

The Shaykh:
If one begins the prayer and has the first part of the time to complete it, and has the first part of the time if he begins it, he completes it and it is not permissible for him to interrupt it.
