Once, when someone was leaving the khaanqah, Hazratjee Moulana Maseehullah (rahmatullahi ‘alaih) advised him as follows: “As far as possible keep good thoughts about people. If you hear something about someone and it can be interpreted in two ways, i.e. in a good way and a bad way, then choose the good interpretation. Always have good thoughts in your mind about people.
On the day of Qiyaamah, Allah Ta‘ala will not question you regarding the good thoughts you had about people but He will definitely question you regarding the bad thoughts you had about others. Bad thoughts about others create evil and corruption. It is for this reason that the sharee‘ah strongly condemns such an act. Today this has become normal for people. No one is prepared to accept their faults. They have no concern of their own faults but keep on looking out at the faults of others. This is a great weakness in us.” (Hazrat Moulana Maseehullah Khan Saaheb [rahmatullahi ‘alaih] – A Brief Biography, pg. 207)
