Ruling on repeating the prayer upon finding semen on the garment

The questioner : The questioner says: A person prayed Maghrib and 'Isha' and the make-up prayer, and he also recited the Qur'an. When he went to the house and undid his garment, he saw semen on his underwear. Does he repeat the prayers he prayed, and is it obligatory?

The Shaykh : The answer is that he does not repeat the prayer he prayed, unless this pre-seminal fluid was after his purification. Yes, if this man who found the semen on his clothing did not perform the full ritual bath, then it is obligatory for him to perform the full ritual bath and repeat the prayers he prayed while in a state of major ritual impurity. But sometimes a person sees the trace of major ritual impurity on his clothing and does not know whether it was from the previous night or the night before that. So, is it considered from the recent previous night or from the earlier night? The answer.
From the recent previous night, from the recent previous night, because what is before the previous night is doubtful, and the default is purity. Likewise, if he slept after the dawn prayer and woke up at midday and found the trace of major ritual impurity on his clothing, and he does not know whether it is from the sleep after the dawn prayer or from the sleep at night, is he required to repeat the dawn prayer?
The answer is no. And make this a rule for yourself: whenever you doubt whether this major ritual impurity is from a previous sleep or a later one, consider it to be from the later one. Yes.
