Traces of Maniy noticed on one's clothes after praying without taking Ghusl for a wet dream

A: Anyone who wakes up and finds wetness on his clothes and is sure that this is Maniy (sperm secretions that are released on orgasm), he has to perform Ghusl (full ritual bath). However, if he does not notice any traces of Maniy until after performing Salah (Prayer), he has to perform Ghusl and repeat the Salah which he offered before making Ghusl. But if he is not sure that this drop is seminal discharge, then the ruling is not applicable to it and his Salah is valid.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
