“Quirrel said Snape-" "Professor Snape, Harry." "Yes, him - Quirrell said he hates me because he hate my father. Is that true?" "Well, they did rather detest each other. Not unlike yourself and Mr Malfoy. Then your father did something Snape could never forgive. " "What?" "He saved his life." "What??" "Yes..." said Dumbledore dreamily.

“No, no, no. I tried to kill you. Your friend Miss Granger accidentally knocked me over as she rushed to set fire to Snape at that Quidditch match. She broke my eye contact with you. Another few seconds and I'd have got you off that broom. I'd have managed it before then if Snape hadn't been muttering a counter-curse, trying to save you.” SnapeQuidditchQuirrell Book:Harry Potter and the Philosopher's Stone Source: Harry Potter and the Philosopher's Stone
