Question:
What is meant by “The default assumption with anything that breaks your wudu (Hadath) is that it happened at the earliest possible moment”? If a person has a problem where if he sits for some time something can appear inside the penis head, walked for 10 mins to the Mosque, prayed and walked back, then at home checks and sees wetness outside, does he assume the prayer is sound? What if, during the prayer, he had a feeling but doesn’t know if something came out?Answer:
In the name of Allah, Most Compassionate, Most Merciful,
Assalam’aleykum,
I pray this finds you in the best of states.
The statement you are asking about has been beautifully explained by Shaykh Abdul-Rahim Reasat in a previous answer:
Practical Steps to Ascertain Validity
You can, in general, assume that your prayers are valid. The default assumption with anything that breaks your wudu (Hadath) is that it happened at the earliest possible moment (Ibn Nujaym, Al Ashbah wa al Nazaʾir). Meaning, if you see some dried discharge on your clothes, you should ask, “When is the last possible moment it could have come out and dried?”
The discharge you see is most likely prostatic fluid (wadi). Let us assume that after the initial discharge, it takes ten minutes to dry. So, the next time you see this discharge on your underwear, you can assume it occurred ten minutes before that.
Then you should see how much there is. If it is more than the excused amount, and you prayed in the last ten minutes, you should repeat the prayer. If it is less than that and therefore excused, you assume that your prayer is valid and carry on with your life. [End quote]

As for feelings during the prayer that bestow simply doubts, they should be ignored because “Certainty is not lifted by a doubt.”[Ibn Nujaym, al-Ashbah wa’l Nadha’ir, and Majallat al-Ahkam al-`Adiliyya]
And Allah knows best.
