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.

One of the most beneficial of remedies is persisting in du’a.

The heart becomes sick, as the body becomes sick, and its remedy is al-Tawbah (repentance) and protection [from transgression]. It becomes rusty as a mirror becomes rusty, and its clarity is obtained by remembrance. It becomes naked as the body becomes naked, and its beautification is al-Taqwa. It becomes hungry and thirsty as the body becomes hungry, and its food and drink are knowledge, love, dependence, repentance and servitude.

Love of Allah is the power of the heart, the sustenance of the heart, the light of the heart.

As you can taste a pot full of food with a spoon likewise someone's tounge can tell you about his heart.

Whoever desires to purify his heart, then let him prefer Allah to his desires

There is no joy for the one who does not bear sadness, there is no sweetness for the one who does not have patience, there is no delight for the one who does not suffer, and there is no relaxation for the one who does not endure fatigue.
