As per Book Seertul Mahdi (written by Mirza bashir M.A ) and Quotatio no. 1085 Quoted by Munshi Zafar that Just like A Jahil Peer, Mirza Ghulam Ahmad Qadyani accepted prostration and even patted three times at the back of a person in ludhyiana . Mirza Qadyani Kept on smiling as per Molvi Abdul Karim ( Qadyani companion)
Comments : Ahmadis Keep on passing comments and pasting pictures of Unknown Mullahs involved in these acts , but cannot comment on Mirza Qadyani (their fake prophet ) to allow Sajda (prostration) to him and kept on smiling . Please find scan attached from Seertul mahdi .
