Sirius bought the Firebolt for Harry through the equivalent of a wizarding mail-order system. Sirius himself explained to Harry in a letter that Hermione's (Emma Watson) cat, Crookshanks, took the order to the Owl Office for him.
In the Prisoner of Azkaban who really gave Harry the Firebolt and why was the black feather included? Sirius Black gave it to him, this is wiki so can easily go to the search feature and search it up by yourself.
This broomstick was arranged for Harry by Professor Minerva McGonagall after he was given a spot on the Gryffindor Quidditch team, as Seeker. He rode this broom in all school Quidditch matches until 1993, when, during a match against Hufflepuff, he was attacked by Dementors and fell off his broom.
Harry Potter has owned several broomsticks. Harry started using the average school broomstick. Later in his first year, Minerva McGonagall sent him a Nimbus 2000 after he became part of Gryffindor Quidditch Team.
Did Professor McGonagall buy Harry the Nimbus 2000?
Harry made the Quidditch team, becoming the youngest Seeker in history. To ensure Potter had his broom, McGonagall bought Harry a Nimbus 2000 broomstick, which was the fastest broom at the time.
To defend her students, McGonagall casts a series of spells Snape's way, but he manages to evade all of them before flying away. But what McGonagall doesn't know is that Snape is actually a double agent working for Dumbledore, so he has no intention of harming her.
The books, however, actually give a good answer to how this was possible. Sirius bought the Firebolt for Harry through the equivalent of a wizarding mail-order system. Sirius himself explained to Harry in a letter that Hermione's (Emma Watson) cat, Crookshanks, took the order to the Owl Office for him.
His dad gave it to him. To elaborate on Icecreamdif's answer, he inherited it as a family heirloom dating back to Hardwin Potter, who married Iolanthe Peverell, granddaughter of the Cloak's original owner Ignotus. It was passed down to the eldest male of each new generation of Potters since then.
This jinx was used by Quirinus Quirrell on Harry Potter's Nimbus 2000 in early November 1991, during a Quidditch match. It was an attempt to murder Harry for Lord Voldemort. No one in the stands detected Quirrell of using this jinx, except Professor Severus Snape, who attempted to save Harry with a counter-curse.
The "seven Potters" and their protectors were: Harry with Rubeus Hagrid, on the flying motorbike of Sirius Black; Hermione Granger with Kingsley Shacklebolt, on a Thestral; Ron Weasley with Nymphadora Tonks, on a broomstick; George Weasley with Remus Lupin, on a broomstick; Fred Weasley with Arthur Weasley, on a ...
Though the Firebolt was confiscated for several months during the 1995–1996 school year by Dolores Umbridge after she gave Harry a lifetime ban from Quidditch, he regained it after she left the school.
The scar is no longer dark, and instead has faded almost to his usual skintone. Scars do fade with time, but J.K Rowling wrote in the book that: "The scar had not pained Harry for nineteen years. All was well." Many people believe the fact the scar has gone dormant after he left Hogwarts is why it faded.
Until the climax of Prisoner of Azkaban, Lupin believed Sirius Black was guilty of murdering 12 Muggles, betraying Lily and James Potter, and killing Peter Pettigrew. He eventually discovered the truth — that Sirius was innocent, and the very much alive Peter was the traitor.
According to Quality Quidditch Supplies, the broom is made of ash wood with a tail of birch twigs and is capable of reaching 150 miles per hour in 10 seconds. In the Harry Potter series, Harry receives the Firebolt as a gift from Sirius Black, his godfather after he escapes the clutches of the Dementors from Azkaban.
It is known that Harry is a descendant of Ignotus Peverell (The brother that received the Invisibility Cloak), and Voldemort is descended from Cadmus Peverell (The brother that received the Resurrection Stone).
Did Snape know Harry was under the Invisibility Cloak?
Dumbledore was doing James a favour by helping him pass down the Invisibility Cloak to his son Harry. Snape definitely knew because in book 4 when Harry sees crouch in Snapes office, he's in his invisibility cloak. As soon as snape sees the golden egg and the map he says 'potters here' to mad eye. Potters here.
As Ilovecats13 and DelphianDragon said, James' father Fleamont quadrupled the family's gold by inventing Sleekeazy's Hair Potion (the same that Hermione used before the Yule Ball to tame her mane). The family fortune was passed down to James, their only child, and then onto Harry. Rowling wrote about it on Pottermore.
Draco, who implies that he is aware of how Sirius Black was supposedly involved in the deaths of Harry's parents, also taunts Harry about the impending threat of Black: "If it was me, I'd want revenge. I'd hunt him down myself."
Sirius states that unlike most other Azkaban prisoners (who often became insane during their terms of imprisonment), he was able to keep his sanity because he knew he was innocent, and also used his Animagus form to ward off the Dementors, who are unable to perceive unsophisticated canine minds.
Sirius left all his belongings, including Kreacher, to his godson. Harry, who had no desire to have anything to do with Kreacher, ordered him to work in the kitchens at Hogwarts with the other house-elves at Dumbledore's suggestion, where he and the other house-elves could keep a close watch on him.
The once shy and awkward Neville Longbottom showed his true bravery during the battle of Hogwarts and eventually became the head of Gryffindor House while also teaching new students Herbology, his favorite subject.
