Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) states:
“Haji Abdur Raheem used to work for my late brother. Once, my first wife complained about him. I immediately summoned him and asked him to stand at the entrance. Thereafter, in her presence I addressed him: ‘She has complained about you.’ I then said to her: ‘You have made a claim regarding some person. Hence you should be able to prove it.’ However, she didn’t have any proof and began saying: ‘You have made fazeehat of me (disgraced me).’ I replied: ‘I do not make fazeehat, rather I give naseehat (advice).’ This practice of complaining about others is evil. It creates enmity within the hearts of people. It then leads to one having doubts as to whether the next person has said something regarding him or not. (Malfoozaat Hakeem-ul-Ummat 1/173)
