How can the phrase "from the narrowness of this world to its vastness" in the saying of Rib'i bin Amir be understood, taking into account that this world is the believer's prison and the disbeliever's paradise, and that disbelievers do as their whims dictate without restraint, unlike Muslims?

The interpretation of Rabi ibn Amir's statement ("from the narrowness of this world to its spaciousness") is the transition from the narrowness of disbelief and turning away from Allah to the spaciousness of faith in Him. This does not contradict the hadith (definition), "The world is a prison for the believer and a paradise for the disbeliever." The meaning of it being a prison for the believer is in comparison to the bliss awaiting him in the Hereafter, and a paradise for the disbeliever in comparison to his torment therein. Ibn Taymiyyah and Ibn al-Qayyim have clarified this, and a story about Ibn Hajar supports this meaning.
