Can one Enter Jannah Just by Wishing?

That's why, Allah tabaraka wa ta'ala says (meaning of the ayah): "Enter you Jannah, because of (the good) which you used to do (in the world)." [Surah An-Nahl (16:32)] A definite, clear cut text that entering Jannah is not by merely wishing like He the Exalted says (meaning of the ayah): "It will not be in accordance with your desires (Muslims), nor those of the people of the Scripture (Jews and Christians), whosoever works evil, will have the recompense thereof". [Surah An-Nisa (4:123)] Whoever does good will be recompensed for it, whoever does evil will be recompensed for it like He the Exalted says (meaning of the ayah): "So whosoever does good equal to the weight of an atom (or a small ant), shall see it. And whosoever does evil equal to the weight of an atom (or a small ant), shall see it." [Surah Az-Zalzalah (99:7-8)] I hope you have got the answer to your question.
