أبي - رحمه الله - قال: حدثنا محمد بن يحيى العطار، عن أحمد بن محمد، عن الحسين ابن يزيد، عن الحسين بن أعين أخي مالك بن أعين، قال: سألت أبا عبد الله عليه السلام عن قول الرجل للرجل: " جزاك الله خيرا " ما يعني به؟ فقال أبو عبد الله عليه السلام: إن الخير نهر في الجنة مخرجه من الكوثر، والكوثر مخرجه من ساق العرش، عليه منازل الأوصياء و شيعتهم، على حافتي ذلك النهر جواري نابتات كلما قلعت واحدة نبتت أخرى باسم ذلك النهر وذلك قول الله عز وجل في كتابه: " فيهن خيرات حسان   " فإذا قال الرجل لصاحبه: " جزاك الله خيرا " فإنما يعني به تلك المنازل التي أعدها الله عز وجل لصفوته وخيرته من خلقه.
1.	My father, may Allah grant him mercy, said: We were told by Muhammed bin Yahya al-‘Attar, from Ahmad bin Muhammed, from Hussain ibn Yazid, from Hussain bin A’yan, the brother from Malik bin A’yan, that he said: I asked Abu Abdillah, peace be upon him, about the saying of one man to another man: «May Allah reward you with goodness», what does he mean with it? Then Abu Abdillah, peace be upon him, said: Indeed, Goodness is a river in Paradise whose emergence is from the Kawthar, and the emergence of Kawthar is from the Leg of the Throne, upon which are the ranks of the Successors and their Shi’a. On the two sides of that river are sprouting maids; whenever one is pulled off, another sprouts with the name of that river, and that is the saying of Allah, Exalted and Glorious is He, in His Book: «In them are beautiful goods». (55:70) So, when one man says to his companion: «May Allah reward you with goodness», he only means by it those ranks which Allah, Exalted and Glorious is He, has prepared for His chosen and selected from among His creation.
