Faesal, who joined the service in 2010, announced his resignation in his Facebook post and said he will share his future plans on Friday.
The 35-year-old alleged "insidious attacks on the special identity of the J&K State and growing culture of intolerance and hate in the mainland India in the name of hypernationalism."
In his post, he said he decided to resign from the Indian Administrative Service (IAS) "To protest against the unabated killings in Kashmir, and lack of any sincere reach-out from the Union Government; the marginalization and invisibilization of around 200 million Indian Muslims at the hands of Hindutva forces reducing them to second-class citizens."
He went on to add that "voices of reason in this country cannot be muzzled for long and the environment of siege will need to end if we wish to usher in true democracy.
Shah Faesal, the 2010 batch IAS topper, Wednesday said he has decided to resign from the Indian Administrative Service to protest the alleged unabated killings in Kashmir and marginalisation of Indian Muslims.
To protest the unabated killings in Kashmir and absence of any credible political initiative from Union Government, I have decided to resign from IAS.
