Ataa al Khurasani said: "I don't advise you to mind your life's affairs because I know that you are covetous to do so, but I advise you to mind the affairs of the Hereafter. Take from this temporary home to the eternal one. Consider this life as something that you have left, I swear by Allah you will leave it. Consider death as something that you have tasted, I swear by Allah you will taste it. And consider the Hereafter as a home that you have visited, I swear by Allah you will be there."
Dhu'n-Noon al-Misri said: "The ailment of the body is in sickness and that of the heart is in sins. A delicious meal cannot benefit the body when the person is sick and likewise, the heart cannot taste the sweetness of worship if it is full of sins."
`Ali ibn Abi Talib said: "Whoever has the following six characteristics does all that is required to make him enter Paradise and avoid Hell: to know Allah subhanahu wa ta`ala and obey him, to know Satan and disobey him, to know the truth and follow it, to know the falsehood and avoid it, to know the life of this world and renounce it, and to know the Hereafter and seek it."
Ibrahim al-Ash`ath said: I heard al-Fudayl saying: "Man's fear of Allah is equal to his knowledge of Him, and his renunciation of the life of this world is equal to his desire of the Hereafter. Whoever acts according to what he knows, Allah will make him successful in what he doesn't know. And whoever is ill-tempered disgraces his honour, religion and generosity."
