Musannaf Ibn Abi Shaybah

Hazrat Muhammad bin Yaqub says that Isa bin Maryam (peace be upon him) said: Do not engage excessively in any speech except the remembrance of God, otherwise your hearts will become hardened. And hardened hearts are far from Allah Almighty, but you do not realize it. Do not look at the sins of people as if you are the Lord. Rather, look at your own sins as if you are a servant. Because people are in only two states: one, those who are afflicted with a trial, and the other, those who are in well-being. Therefore, have mercy on those who are afflicted and be grateful to Allah Almighty for well-being.
