Ali al-Tantawi, Allah have mercy on him, was asked about the most beautiful piece of wisdom he read in his lifetime, to which he replied: 

“I have read for over 70 years, and in that time not found a word of wisdom more beautiful that what ibn al-Jawzi said:

“The hardship that comes with obedience [to Allah] eventually disappears, but its reward remains. And, the pleasure of sin eventually disappears, but its punishment remains.

Be with Allah, and do not concern yourself [with anything else]. Stretch out your hands to Him in the darkness of night, and say: “Master, there is neither anything pleasant in this world if not for Your remembrance, nor in the afterlife if not for Your pardon. Indeed, there would be nothing pleasant in paradise, if not for seeing You.”

Forgive, and forget. Leave the creation to their creator. Because we are leaving; both us and them. Do good deeds, no matter how small they may seem, because you do not know which one of those deeds could enter you into paradise. “
