Abu Sa’id Al-Khudri related that the Messenger of Allah (SAW) said: Oh Abu Sa’id, whoever is pleased with Allah as Lord, with Islam as religion, and with Muhammad as Prophet, Jannah is certainly his. And Abu Sa’id was amazed at this and said: Say it to me again, oh Messenger of Allah! And so He did. Then the Messenger of Allah (SAW) said: And there is something else, by which a servant is raised up in Jannah one hundred levels, between every two levels like that which is between heaven and earth. He said: And what is it, oh Messenger of Allah? He said: Jihad for the sake of Allah! Jihad for the sake of Allah!
