298. Muhammad Bin Yahya, from Ahmad Bin Muhammad, from Al-Husayn Bin Yazeed Al-Nawfaly, from Al-Husayn Bin Ayn the brother of Malik Bin Ayn who said: I asked Abu Abdullah about the words which a person would say to another person, ‘جَزَاكَ اللَّهُ خَيْراً’ ‘May Allah (azwj) Reward you with goodness (Khair)’, what is meant by it?’ So Abu Abdullah said: ‘Khair’ is a river in the Paradise, a tributary from Al-Kawsar. And Al-Kawsar comes out from the Pillar of the Throne around which are houses of the successors , and their Shites. On the banks of that river maids (Houries) grow. Every time one is taken, another one grows in its place, and they have been named after that river (Khair). And that is the Statement of the High (azwj): “[5:70] In them are goodly things (Khair), beautiful ones”. So if the man says to his companion, ‘May Allah (azwj) Reward you with goodness (Khaira)’, it means by that those dwellings which Allah (azwj) Mighty and Majestic has Prepared for His (azwj) elite, and the good ones from His (azwj) creatures’.
