Malikabad area residents and police sources allege the man, who they claim was not of sound mind, called himself a prophet.
Shabqadar Station House Officer Murtaza Khan, however, denies the allegations, saying that the crime appears to be a case of personal enmity.
The man's family registered a First-Information Report against unknown assailants.
A Supreme Court judgment issued regarding the Salman Taseer murder case in October last year said that in many cases registered in respect of blasphemy offence, false allegations are levelled for extraneous purposes and in the absence of adequate safeguards against misapplication or misuse of such law by motivated persons, the persons falsely accused of that offence suffer beyond proportion or repair.
