What is the nature of the white spot found on underwear after waking up or during the day, which is transparent when it comes out and changes to a thick consistency on clothing, and is it necessary to change underwear because of it, or is it sufficient to wipe it with water to complete the prayer?
What you mention may be merely an illusion, a whisper [from Satan], or a vein [pulsating], so pay no mind to these doubts. If you are certain that secretions have exited the penis, then it is most likely madhiy (pre-seminal fluid). The method for purifying from it is explained in Fatwa no. 59304.
