I am a disabled man who is wheelchair bound, Alhamdulillah. I had wet dream before Fajr in some night. Due to the weakness of my body I could not make Ghusl, nor could I change my clothes except in the day. I did not want to miss Fajr prayer that day so I just made Wudu’ and prayed. Is this permissible or not? What shall I do if it was not permissible?
Praise be to Allah.
If a person becomes Junub as the result of a wet dream or intercourse, then he must do Ghusl, because Allah says (interpretation of the meaning):
“O you who believe! Approach not As‑Salah (the prayer) when you are in a drunken state until you know (the meaning) of what you utter, nor when you are in a state of Janabah (i.e. in a state of sexual impurity and have not yet taken a bath), except when travelling on the road (without enough water, or just passing through a mosque), till you wash your whole body”[An-Nisa’ 4:43]
If he cannot do Ghusl because there is no water available, or because he is unable to use it, then he may do Tayammum and prayer, because Allah says (interpretation of the meaning):
“But if you are ill or on a journey, or any of you comes after answering the call of nature, or you have been in contact with women (i.e. sexual intercourse), and you find no water, then perform Tayammum with clean earth and rub therewith your faces and hands. Allah does not want to place you in difficulty, but He wants to purify you, and to complete His Favor to you that you may be thankful”[Al-Ma’idah 5:6]
Similarly, if a person has a wet dream and is afraid that he will become sick if he uses cold water, and he cannot find anything to heat it with, or the water is far away from him and he cannot reach it, and he cannot find anyone to bring it to him, then he may do Tayammum and pray.
Ibn Qudamah (may Allah have mercy on him) said in Al-Mughni (1/151): If a person is sick and cannot move, and he cannot find anyone to bring water to him, then he is like one who has no water, because he has no way to get the water.
If he has someone who can bring the water to him before the time for prayer ends, then he is like one who has water.
If he is afraid that the time for prayer will end before the water can be brought to him, then Ibn Abi Mousa said: He can do Tayammum, and he does not have to repeat the prayer. This is the view of Al-Hasan. End quote.
As for Wudu’, it cannot take the place of Ghusl.
What you should have done, if you could not find anyone to help you to do Ghusl, was to wash whatever you could of your body, such as the head, face, hands and feet, then do Tayammum, and pray with this Tayammum.
Based on this, you have to repeat that prayer.
Mani is Tahir (pure) according to the more correct of the two scholarly opinions, so you do not have to wash or change your clothes.
We ask Allah to give you well-being in your religious and worldly affairs.
And Allah knows best.
