Musannaf Ibn Abi Shaybah

Hazrat Muhammad bin Yaqub narrates that Hazrat Isa bin Maryam said: Do not speak of anything except the remembrance of Allah, for by doing so your hearts will become hardened, and hardened hearts are far from Allah. But you do not know. Do not look at the sins of the servants as if you are their Lord; rather, look at your own sins as if you are a servant. For people are of two kinds: those who are afflicted with trials, and those who are in well-being. Therefore, have mercy on those who are afflicted, and praise Allah for well-being.
