If someone is going to say things to me like "You won't enter jannah unless you love the prophet more than you love yourself", you'd better back it up with Qur'anic proof. If you can't find that proof, then perhaps you'd better re-evaluate the stuff you're parroting that you've heard from other people.
Believe what you want. I support that completely. But I will not accept the hadith as proof of an assertion in lieu of evidence from the Qur'an.
3:78 "And from among them is a group who twist their tongues with the Book so that you may think it is from the Book, while it is not from the Book, and they say it is from God while it is not from God, and they say about God lies while they know."
So bring it.
