Translation of the verse 8 from Surah Fussilat : Number of verses 54 - - page 477 - Part 24.
Truly, those who believe (in the Oneness of Allah Islamic Monotheism, and in His Messenger Muhammad SAW) and do righteous good deeds, for them will be an endless reward that will never stop (i.e. Paradise).
Indeed, those who believe and do righteous deeds - for them is a reward uninterrupted.
(41:8) As to those who have faith and do good works, surely theirs shall be a never-ending reward. *10
*10) The words ajrun ghaira mamnun in the original have two other meanings also: (1) That it will be a reward which will never decrease and diminish; and (2) that this reward will not be given with reminders of good done, like the gift made by a miserly person, who keeps on reminding the beneficiary of his favour if at all he gives away anything.
