Ruling on the prayer of one who finds semen on his garment after several days

Question:
I found semen on my garment after several days. What is the ruling on the prayers I performed during those days?

Answer:
If you find semen on your garment after several days, you must repeat the prayers you performed after your last sleep. You must repeat the prayer, perform the full ritual bath, and repeat the prayer you prayed after sleeping. This is because this is the point of certainty: it is certain that the semen appeared in the last sleep, whereas the time before that is doubtful. So, if you find this semen after sleeping until the yellow light of dawn on Monday, repeat the Fajr prayer you prayed. If you find this semen after sleeping for the midday prayer or after sleeping for the afternoon prayer, and you prayed the sunset prayer with it, repeat the Maghrib prayer. Likewise, for the last sleep, you repeat the prayer that follows it, because that is where the major ritual impurity occurred.
