Praise be to Allaah.
Firstly:
It seems
that this wetness that you feel is madhiy and not maniy, the emission of
which means that you must do ghusl.
Based on
this, you do not have to do ghusl when it is emitted, you only have to do
wudoo, because the emission of madhiy invalidates wudoo’, as the Prophet
(peace and blessings of Allaah be upon him) said concerning madhiy:
“Wudoo’ is required for it.” Narrated by al-Bukhaari and Muslim.
Ibn Qudaamah
(may Allaah have mercy on him) said in al-Mughni (1/168): The
scholars are unanimously agreed that the emission of madhiy invalidates
wudoo’
Secondly:
It must be
noted that madhiy is naajis (impure), and any part of the body that it
touches must be washed. As for clothing, Islam is lenient about purifying it
so as to ward off hardship. It is sufficient for you to take a handful of
water and sprinkle it on the place that has been touched by madhiy, because
when the Messenger (peace and blessings of Allaah be upon him) was
asked about how to cleanse a garment of madhiy, he said: “It is sufficient
for you to take a handful of water and sprinkle your garment where you think
the madhiy touched it.” Narrated by al-Tirmidhi (115); classed as hasan by
al-Albaani in Saheeh al-Tirmidhi.
We have
explained the difference between madhiy and maniy and the rulings on them in
the answer to question no. 2458, to which you may refer for more
information.
And Allaah
knows best.
