Imam Waqt Hazrat Abdullah bin Mubarak (may Allah have mercy on him) himself narrates an incident that once, during a trip to Syria, I borrowed a pen from someone and then forgot to write with it. When I returned to my homeland, Marw, I saw that the pen had come with me. I immediately decided to travel and returned the pen. Even though in those days, the thought of thick bags of brass for returning a pen from Marw was unimaginable. His famous saying is: "One dirham of doubtful wealth is better than one hundred thousand dirhams of lawful wealth."
(Muqaddimah Kitab al-Birr, p. 35)
These are a few glimpses of the piety and God-fearingness of Allah's accepted servants, from which we learn how much these gentlemen cared about their high position and how much caution they exercised and cultivated the habit of fulfilling rights in order to protect their religious honor. The result was that such blessings appeared in their services that even among the people after the dissemination of the world, those gentlemen who made the closeness of these pure souls their guidance tried to adopt their qualities, and Allah Almighty opened the doors of acceptance for them as well.
