Tafsir of Sad 38:54

Verily, this is Our provision which will never finish. This is like the Ayat:

ما عندكم ينفد وما عند الله باق

Whatever is with you, will be exhausted, and whatever is with Allah will remain. (16:96)

عطاء غير مجذوذ

a gift without an end. (11:108)

لهم أجر غير ممنون

for them is a reward that will never come to an end. (84:25)

أكلها دآيم وظلها تلك عقبى الذين اتقوا وعقبى الكفرين النار

its provision is eternal and so is its shade; this is the end of those who have Taqwa, and the end (final destination) of the disbelievers is Fire. (13:35) And there are many similar Ayat
