When a person wakes up from sleep and finds wetness on his clothes, there are three possible scenarios:
1. Certainty That It Is Semen (Mani)
- Ruling: Ghusl is obligatory.
- It makes no difference whether he remembers having a wet dream or not, because ghusl becomes obligatory upon the discharge of semen.
2. Certainty That It Is Not Semen
- Ruling: Ghusl is not obligatory.
- However, the wet spot must be washed, as it is considered like urine in ruling.
3. Doubt Whether It Is Semen or Not
This situation has further details:
a) If He Remembers a Wet Dream
- The wetness is considered semen, and ghusl is obligatory.
- Evidence: The hadith of Umm Salamah (RA):
“When a woman sees in her sleep what a man sees, does she have to perform ghusl?”
The Prophet ﷺ replied:
«نَعَمْ إِذَا رَأَتِ الْمَاءَ»
“Yes, if she sees the water (semen).”
[Sahih Muslim, Kitab al-Hayd, Bab Wujub al-Ghusl ‘ala al-Mar’ah bi-Khuruj al-Mani Minha, Hadith: 313]
b) If He Did Not See Anything in a Dream
- If he thought about intercourse before sleeping, the wetness is considered madhy (pre-ejaculatory fluid).
- Madhy does not require ghusl, but the private part must be washed for purification.
c) If He Had No Such Thoughts Before Sleeping
- Scholars differ:
- One opinion: Ghusl is required out of precaution.
- Stronger opinion: Ghusl is not obligatory.
- Reason: The principle is barā’at al-dhimmah (freedom from obligation) — unless there is certain proof, no ruling of obligation can be imposed.
