Musannaf Ibn Abi Shaybah

Hazrat Abdul Malik bin Umair, may Allah have mercy on him, said that a man advised his son to show despair regarding what is in the hands of people, because this is true independence. And protect yourself from asking for needs, because this is the poverty of the time. And protect yourself from those things for which you would have to make excuses. And when you pray, pray in such a way as if it is your last prayer; do not think that you will get another chance. And if you are able to make your today better than your yesterday, and your tomorrow better than your today, then be sure to do so.
