One may ask, “How is this a proof?” Great question! Well, if a person is a fraud, there are few possible reasons why he would claim to be a Prophet, right? Fame, power, and women are common ones.

Yes, he might just be crazy enough to make the claim for the greater good, unite his people, and make the world a better place. In his mind, he could’ve justified it.

BUT then why pray so much? As you may know, in Islam, it is mandatory for Muslims to pray the 5 daily prayers. That’s hard enough! Let’s excuse that and say, “Fine, that’s possibly to make human beings develop self-control.”

But how was Prophet Muhammad (ﷺ)? Yes, like every other Muslim, he would make the 5 prayers and he would do it regardless of what was going on. But it was not just those. He would do a lot of voluntary prayers every day. And at night, when he could’ve lowered his guard, given up his disguise, or at least rested, he would sleep a little, wake up, and then pray for hours before dawn came about.Why would an imposter give up sleep for something he made up? He could’ve just prayed when he woke up. But nope! In fact, he would pray so much that his wife ‘Aisha (ra) is reported to have asked him why he’s praying so much that his feet would swell, after which he gave his famous response, “Should I not be a grateful servant?” [Sources: Sahih Bukhari 1078 & Sahih Muslim 2819]
