Imam Malik (Rahimahullah) said: “I noticed people who seemed to be faultless and were considered to be good people but they began disclosing the faults of others. As a result, People started finding faults in them. And I noticed people who seemed to be bad and sinful people. But they refrained from exposing the shortcomings of others. As a result, Allah concealed their faults” (Khulasatul Athar, Vol: 4, Pg: 195)
