Akal Takht jathedar Gurbachan Singh pronounced "tankhah" (religious punishment as per Sikh tenets) based on a probe conducted by the Shiromani Gurdwara Parbandhak Committee into the charges levelled against the minister.
A complainant had last month alleged that Maluka had taken part in a private function in Bhatinda where 'ardas' (Sikh prayer) was "intentionally" distorted.
Maluka appeared before the five Sikh head priests who questioned him about the "blasphemous" act.
Singh, while pronouncing the punishment, directed him to clean utensils in the community kitchen of the Golden Temple the shoes of devotees for an hour daily for three days on the trot.
