The ruling on one who discovers the discharge of something from him after the prayer

This is a message received by the program from listener (A. A. A.) from Iraq. He begins by saying: In the name of Allah, the Most Gracious, the Most Merciful. Peace be upon you and Allah’s mercy and blessings. Greetings to your esteemed program. After that, my first question: If a person prays and then discovers after the prayer that something has been discharged from him, does he have to repeat the prayer or not? Please inform us; may Allah reward you.
Answer: If a person prays and then discovers after the prayer that urine or pre-seminal fluid has come out of him, there is a detailed ruling: If he is certain that this came out during the prayer, he must repeat it. He must perform ablution, clean himself from the urine or the pre-seminal fluid, wash his penis and testicles from the pre-seminal fluid, perform the prescribed ablution, and repeat the prayer. However, if he has doubt and does not know whether this came out during the prayer or after the prayer, he does not have to repeat it. If he has doubt about this urine whose trace he saw, or the pre-seminal fluid, whether it was during the prayer or whether it came out after the prayer, he does not have to repeat the prayer.
