Yes, there will be marriage in Paradise, but its exact nature is unknown because there will not be the nafs (a negative force within humans that prompts them to do evil) there. Islamic scholars state: "Things in this world are a reflection, and an original source should exist for each reflection. A reflection is not formed if its original does not exist. The original, genuine forms of all worldly things exist in Paradise." If one eats various fruit in one's dream, one will see when one wakes up that it was not real. Similarly, the inhabitants of Paradise will see the things in the world as something dreamt of, and they will attain the real ones. Worldly things are like the shadows and copies of their counterparts in Paradise. As a matter of fact, a hadith-i sharif says, "People are asleep. They will wake up upon dying." When we are transferred to the next world upon dying, worldly beings will be like those we see in our dreams. A hadith-i sharif says (what means): (The similarity between the blessings in Paradise and those in the world is in name only.) [Bayhaqi] It is stated that a person whose two days are the same is at loss. Accordingly, blessings will be increased each passing day in the afterworld. Every day, people will get different and much more pleasure from the same blessings. Moreover, they will be bestowed different bounties and different favors each day. No doubt should be harbored at all about Allahu ta'ala's power. Humans try to compare what they do not know to what they know, but something unknown cannot be compared to something known. It is declared in a hadith-i sharif: (The world is like Paradise when compared to the womb and like a garbage dump when compared to Paradise.) [Ma'rifatnama] Can Paradise ever be compared with a garbage dump? Just as it is impossible for a baby in the womb of its mother to know that it will be born and face various events, so it is impossible for a Believer who will go to Paradise to know the blessings he/she will attain there. A hadith-i sharif says (what means): (In Paradise, there are blessings that are never heard and cannot even be imagined.) [Muslim] Accordingly, the real form of marriage will exist in Paradise. Everybody will appear very beautiful to his/her spouse, and he/she will say that there is no one more beautiful or more handsome than his/her spouse. In Paradise, the delights of marriage, like all delights, will increase every day, and it will continue in this manner forever. The fact that there will be marriage in Paradise is established by Qur'anic verses and Prophetic sayings. When the blessings that will be granted to good people are described in the Qur'an al-karim, the following is said: (Besides, We will wed them to houris having kohl-rimmed eyes [having beautiful eyes].) [Ad-Dukhan 54] (We have created those with beautiful eyes anew for the ones whose books of records will be given from their right. We have made them virgins, devoted to their spouses, and of equal age.) [Al-Waqi'ah 35-38]
