The discharge of pre-seminal fluid without knowledge and the validity of the prayer

The questioner:
He says: Honorable Shaykh, may Allah grant you success, if a person passes pre-seminal fluid, the time for prayer arrives, he performs ablution, and he does not know about it

The Shaykh:
For that.

The questioner:
If pre-seminal fluid comes out of a person, yes, and the time for prayer arrives, and he performs the ablution without knowing that it had come out of him, and he prays, is he excused and is his prayer accepted?

The Shaykh:
If he does not know that it came out before the prayer or during the prayer, he does not know when it came out, then the prayer is valid. But if he knows that it came out before the prayer and did not perform the ablution, or if he knows that it came out during the prayer, then his prayer is invalid and he must repeat it, because the discharge of pre-seminal fluid is one of the things that break the ablution. Yes.
