So this is the argument used against Muhammed, the prophet of Islam. But that is because there is documented evidence that suggests he possibly had some of the symptoms of TLE.(not saying he had it though) With Paul, there is no evidence of such:
Muhammad and Temporal Lobe Epilepsy (TLE)
By Ali Sina
The Physical Effects of Muhammad’s Ecstatic Experiences:
Here is how Muhammad described his mystical experiences:
“The Revelation is always brought to me by an angel: sometimes it is delivered to me as the beating sound of the bell–and this is the hardest experience for me; but sometimes the angel appears to me in the shape of a human and speaks to me.” 
“Those who saw the Prophet (pbuh) in this state relate that his condition would change. Sometimes he would stay motionless as if some terribly heavy load was pressed on him and, even in the coldest day, drops of sweat would fall from his forehead”  At other times he would move his lips.
Ibn Sa’d says, “at the moment of inspiration, anxiety pressed upon the Prophet, and his countenance was troubled” 
“He fell to the ground like one intoxicated or overcome by sleep; and in the coldest day his forehead would be bedewed with large drops of perspiration. Inspiration descended unexpectedly, and without any previous warning.” 
“Then Allah’s Apostle returned with that experience; and the muscles between his neck and shoulders were trembling till he came upon Khadija (his wife) and said, “Cover me!” They covered him, and when the state of fear was over”  and 
All these are symptoms of Temporal Lobe Epilepsy. The following is a partial list of the Temporal Lobe Seizure Symptoms & Signs as defined in health.allrefer.com
Hallucinations or illusions such as hearing voices when no one has spoken, seeing patterns, lights, beings or objects that aren’t there
Rhythmic muscle contraction Muscle cramps are involuntary and often painful contractions of the muscles which produce a hard, bulging muscle
Abdominal pain or discomfort.
Sudden, intense emotion such as fear.
Muscle twitching (fasciculation) is the result of spontaneous local muscle contractions that are involuntary and typically only affect individual muscle groups. This twitching does not cause pain.
Abnormal mouth behaviors
Abnormal head movements
Rapid heart rate/pulse
Changes in vision, speech, thought, awareness, personality
Loss of memory (amnesia) regarding events around the seizure (partial complex seizure)
All the above symptoms were present in Muhammad during the moments that he was allegedly receiving revelations.
He had visions (hallucinations) of seeing an angel or a light and of hearing voices.
He experienced bodily spasms and excruciating abdominal pain and discomfort
He was overwhelmed by sudden emotions of anxiety and fear
He had twitching in his neck muscles
He had uncontrollable lip movement
He sweated even during cold days.
His face flushed. His countenance was troubled.
He had rapid heart palpitation
He had loss of memory. (There is a tradition that states Muhammad was bewitched and used to think that he had sexual relations with his wives when he actually had not. 
It is also interesting to note that Muhammad’s hallucination was not limited to seeing the Angel Gabriel but he also claimed seeing Jinns and even in one occasion while praying in the mosque he started struggling with an imaginary person and later said “Satan came in front of me and tried to interrupt my prayer, but Allah gave me an upper hand on him and I choked him. No doubt, I thought of tying him to one of the pillars of the mosque till you get up in the morning and see him. Then I remembered the statement of Prophet Solomon, ‘My Lord ! Bestow on me a kingdom such as shall not belong to any other after me.’ Then Allah made him (Satan) return with his head down (humiliated).” 
Muhammad’s belief in Satan was such that he seemed to think that not even he is immune from his whisperings. 
One of the embarrassing events in Muhammad’s life occurred when Satan put words in his mouth.
Tabari says: “When the messenger of God saw how his tribe turned their backs on him and was grieved to see them shunning the message he had brought to them from God, he longed in his soul that something would come to him from God which would reconcile him with his tribe. With his love for his tribe and his eagerness for their welfare it would have delighted him if some of the difficulties which they made for him could have been smoothed out, and he debated with himself and fervently desired such an outcome. Then God revealed:
“By the Star when it sets, your comrade does not err, nor is he deceived; nor does he speak out of (his own) desire…”
and when he came to the words:
Have you thought upon al-Lat and al-Uzza and Manat, the third, the other?
Satan cast on his tongue, because of his inner debates and what he desired to bring to his people, the words:
"These are the high flying cranes; verily their intercession is accepted with approval.
The Quraysh left delighted by the mention of their gods. Amity was restored and the news of that reached the followers of Muhmmad who at his behest had migrated to Abyssina and some of them returned. Muhammad realizing the consequence of this is giving up on his monopoly on God and the contradiction that it entails, claimed those verses and his Allah consoled him saying, “Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom”: 22:52
