Whatever is with you, will be exhausted, and whatever with Allah (of good deeds) will remain. And those who are patient, We will certainly pay them a reward in proportion to the best of what they used to do. [ Qur'an - 16:96 ]
if we only knew. Whatever we have will be exhausted, meaning, it will come to an end and will vanish, because it is only there for a certain, limited time, and what is with Allah will remain, meaning, His reward for us in Paradise will remain, without interruption or end, because it is eternal and will never change nor disappear.
And to those who are patient, We will certainly grant them their rewards in proportion to the best of what they used to do, here the Lord swears, with the Lam of affirmation, that He will reward the patient for the best of their deeds, i.e., He will forgive them for their bad deeds. [ Tafseer Ibn Katheer ]
May increase our patients and forgive all our sins.
