There will come a day when a person would be willing to give everything they ever loved, everything they ever owned, everything they ever chased in this life, everything between the heavens and earth...just for the chance to come back here and make just one sajdah (prostration). Just one.
And so in the heart of such a believer is a sort of paradise. That is the paradise that Ibn Taymiyyah, may Allah have mercy on his soul, spoke of when he said: 'Truly, there is a Heaven in this world, [and] whoever does not enter it, will not enter the Heaven of the next world.' And in that heaven, complete peace is not something of a moment. It is a state, eternal.
