Him

"Truly in the heart there is a sadness that cannot be removed

except with the happiness of knowing Allah

and being true to Him.

And in it there is an emptiness that cannot be filled

except with love for Him and by turning to Him

and always remembering Him.

And if a person were given all of the world and what is in it,

it would not fill this emptiness."

(Ibn Al-Qayyim)
