While fans of the fantasy series might rejoice at such a request, it seemed like an odd ask from the 'Candy Shop' rapper.
It all started when 50 did the Ice Bucket Challenge, but instead of nominating Floyd to pour cold water over his head, he suggested something a little different.
The footage re-emerged online this week, showing 50 asking the heavy weight to take part in a 'special' challenge, taking aim at the boxer's rumoured trouble reading.
According to 50, he was willing to donate $750,000, if the boxing champ could he could 'read one full page of a Harry Potter book'.
"F*** the bucket of ice," the rapper ended the video, before surprisingly throwing said bucket of ice off of a balcony.
So that's one page, $750,000 for a charity of Mayweather's choosing. Seems like a good deal.
And, other's thought so too, with Jimmy Kimmel; even saying that he'd host the live reading.
"I got a phone call from my man Jimmy Kimmel, and Jimmy Kimmel said that if Floyd accepts the challenge, then he will put it on the actual show," 50 noted.
"So, you can read it on the show. We don’t want to put pressure on you. We know you can’t pronounce those words in that Harry Potter book, so we are going to let you read Cat in the Hat."
However, to Mayweather didn't fancy the challenge and in response posted donation cheques as a response.

Mayweather later had to addressed the rumours about his literacy skills in 2014, during a radio show appearance.
"I don't get paid to read radio drops. I'm capable of having a bad day. I'm not perfect. You know as well as I know, they edited the tape how they wanted to do it."
"Making fun of a person because they can't read is not funny. It's tragic. If I really couldn't read, it would make my accomplishments that much more amazing."
Which, really is fair enough.
And Mayweather probably wouldn't have time to take part in a televised reading with his upcoming fight to 'Dangerous' Don Moore coming up.
The pair are set to go head to head on 14 May on the helipad of Dubai's Burj Al Arab hotel.
Moore holds an impressive record and it is unclear as of yet how the fight will be judged, but it definitely won't involve Harry Potter.
