Who are the al-hoor al-ayn in paradise?

In Islam, the term "al-hoor al-ayn" refers to the beautiful and pure companions that are promised to believers in Paradise. These companions are often described as being of exceptional beauty and radiance, and are a symbol of the rewards that await believers in the afterlife. The concept of al-hoor al-ayn is mentioned several times in the Qur'an, and they are described as being a reward for those who believe in God and follow His teachings. The sources are quite clear in their description: “Verily, We have created them (maidens) of special creation. And made them virgins. Loving (their husbands only), of equal age” (Qur’an al-Waaqi’ah 56:35-37) “And (there will be) Hoor (fair females) with wide lovely eyes. Like preserved pearls.” (Qur'an al-Waqi’ah 56:22-23) The Messenger of Allah said: "No woman annoys her husband but his wife among Hooris (of Paradise) said: 'Do not annoy him, may Allah destroy you, for he is just a temporary guest with you and soon he will leave you and join us."' (Ibn Majah) The Messenger of Allah (saw) said: “The first group will enter Paradise looking like the moon on the night when it is full, and those who follow them will be like the brightest shining star in the sky. Their hearts will be as one, and there will be no hatred or jealousy among them. Each man will have two wives from among al-hoor al-ayn, the marrow of whose calves can be seen from beneath the bone and flesh.” (Sahih al-Bukhari 3014; Muslim, 2843) The Messenger of Allah (saw) said: “If a woman from among the people of Paradise were to look out over the earth, she would illuminate everything that is in between them, and would fill everything that is in between them with fragrance. And the scarf on her head is better than this world and everything in it.” The Prophet Muhammad (saw) said that: “Every man in heaven will go to 72 of the creatures of Allah (hoors) and 2 of the women of mankind, these two women are superior to the creatures of Allah (hoors) with their worshipping (good deeds) they had performed in this world.” (Bayhaqi, al-Bas wa’n-Nushur; Tabari, Tafsir; Abu Yala, Ibn Hajar, Fathu’l-Baari, Tabarani and others) The mufassir al-Sa’di (ra) stated: “And (there will be) Hoor (fair females) with wide lovely eyes”. Al-Hawra’ is a woman in whose eyes are lined with kohl, beautiful and bright. Al-‘iyn refers to beautiful and huge eyes. The beauty of eyes in the female is one of the greatest signs of beauty... they have no faults of blemishes of any kind, rather they are beautiful in all ways. Every time you gaze upon her, you see nothing but that which gladdens the heart. (Tafseer al-Sa’di, p. 991)
