This wordly life is like a shadow. If you try to catch it, you will never be able to do so. If you turn your back towards it, it has no choice but to follow you.

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 keys to the life of the heart lie in reflecting upon the Quran, being humble before Allah in secret, and leaving sins.

And if a person were given all of the world and what is in it, it would not fill his emptiness.

The ibtilaa' (testing) of the believer is like medicine for him. It cures him from illness. Had the illness remained it would destroy him or diminish his reward and level (in the hereafter). The tests and the trials extract these illnesses from him and prepare him for the perfect reward and the highest of degrees (in the life to come).

O people who take pleasure in a life that will vanish, falling in love with a fading shadow is sheer stupidity

Doom comes about because of neglecting to evaluate one's self and because of just following one's whims.
