What is the ruling regarding Friday prayer performed with an impure garment, the impurity of which was unknown at the time of the prayer, and how can what was missed be made up, if necessary?

If a person sees semen on his garment, and no one else sleeps in it, he must perform ghusl (definition) (ritual bath) and repeat the prayers from the last sleep he had in it. This is unless he is more certain that it was discharged before the last sleep, in which case he should repeat the prayers from the sleep he is more certain it was discharged during. If the semen is wet, it is from the last sleep; but if it is dry, it is from the first sleep. He should repeat the Dhuhr prayer instead of Jumu'ah (Friday prayer) and Maghrib if he had prayed them. It is recommended to wash the semen from the garment.
