"The greatest punishment for sins is that a person forgets his own self, rejects his shared portion bestowed by Allah Almighty, and sells Allah's bounty for a miserable and insignificant price. Consequently, the sinful servant loses something for which there is absolutely no substitute.

The poet says:

مِنْ كُلِّ شَيْءٍ إِذَا ضَيَّعْتَهُ عِوَضُ

وَمَا مِنَ اللهِ إِنْ ضَيَّعْتَهُ عِوَضُ

Therefore, Allah grants a substitute for everything except Himself, and nothing can ever be a substitute for Allah.

(Everything you are separated from has a replacement, but if you are separated from Allah, there is no replacement for Him.)"
