The sea of pleasures may drown its owner and the swimmer fears to open his eyes under the water.

When Allah granted Prophet Yoosuf (`alayhis-Salaam) physical beauty it caused him to be locked up in the prison; but when Allah granted him knowledge (when he interpreted the dream of the king) it not only took him out of prison, but elevated his rank in society, clearly showing us the virtue of knowledge and that physical beauty does not mean anything.

A true believer does not fear physical death, rather he fears the death of his heart

Truly in the heart there is a void that can not be removed except with the company of Allah. And in it there is a sadness that can not be removed except with the happiness of knowing Allah and being true to Him. And in it there is an emptiness that can not 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.

Every gulp of air that goes out in a cause other than the cause of Allah will turn to sorrow and regret on the Day of Judgement.

Yearning for Allah and His meeting is like the gentle breeze blowing upon the heart, extinguishing the blaze of the Dunya. Whosoever caused his heart to settle with his Lord shall be in a state, calm and tranquility, and whosoever sent it amongst the people shall be disturbed and excessively perturbed.

The heart will rest and feel relief if it is settled with Allah. And it will worry and feel anxious if it is settled with the people.
