Fussilet 8:

•  Ama, iman edip, salih amel işleyenleri ise, kesintisiz bir mükafat (أَجْرٌ غَيْرُ مَمْنُونٍ) beklemektedir.
  (
  The words ajrun ghaira mamnun(أَجْرٌ غَيْرُ مَمْنُونٍ) 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 favor if at all he gives away anything.  ET
