If a man's patience is stronger than his whims and desires, then he is like an angel, but if his whims and desires are stronger than his patience, then he is like a devil. If his desire for food, drink and sex is stronger than his patience, then he is no better than an animal.

Beware of every hour and how it passes, and only spend it in the best possible way, do not neglect yourself, but render it accustomed to the noblest and best of actions, and send to your grave that which will please you when you arrive to it.

From the perfection of Allah's ihsan is that He allows His slave to taste the bitterness of the break before the sweetness of the mend. So He does not break his believing slave, except to mend him. And He does not withhold from him, except to give him. And He does not test him (with hardship), except to cure him.

There are no means of attaining faith and certainty except through the Qur'an.
