A seeker wrote, ‘The condition of this lowly writer is that the (spiritual) ailment of suspicion (bud-gumani/soo-e-dhan) is deeply rooted in my heart for a long duration. I become suspicious of fellow brothers and sisters on very minute things. I have tried many remedies according to my sub-standard intelligience. However, this ailment did not go away.
Please, recommend a remedy to cure this destructive (spiritual) disease.
Hakim al Umma Maulana Ashraf Ali Thanvi (Allah have mercy on him) replied,
‘Whenever, thoughts of suspicion come to mind (qalb)
1. Firstly, sit alone and remind yourself that Allah has forbidden suspicion. A sin has been committed. There are (fair) chances of getting punishment for sinful actions. O nafs! How are you going to endure this punishment?
2. After this reflection repent.
3. Make supplication (dua). O Allah ! Cleanse my heart (and mind).
4. Make supplication for the individual you had suspicions. O Allah! Bestow him with the blessings of both the worlds.
Do this three times daily. If the affects (of suspicious thoughts) remains then repeat it for 2 or 3 days. If it persist even after this, then approach this individual and tell him that I had baseless suspicion about you. Please, forgive me and make supplication for me that this (spiritual ailment) is cured.’
