The state Congress chief has accused Badal of pitting Sikh religious leaders against each other as part of his agenda of "controlled destabilisation" in the state.
"Amarinder has no right to question the integrity and sincerity of Chief Minister Parkash Singh Badal who has devoted his entire life to serve Punjab and made great sacrifices for the state suffering the hardships of imprisonment," SAD spokesperson and education minister Daljit Singh Cheema said.
Unidentified assailants had on May 17 opened fire at the cavalcade of Dhadrianwale in which he had a narrow escape but his aide Bhupinder Singh Khalsa of Khasi Kalan died.
"Instead of politicising the issue, Amarinder and his party's 'B' team Aam Aadmi Party should come forward and cooperate in maintaining peaceful atmosphere in Punjab," he said.
"The state Congress chief would do very well to remember his own betrayals to Punjab instead of casting aspersions on the integrity of Badal," the SAD leader said.
