Gurudwara Baoli Sahib at Sialkot City
The Gurdwara Baoli Sahib is located at a distance of two hundred meters from Gurdwara Bair Sahib. It was built over the site where once the house of Maula Karar stood. He was afraid to meet Sat Gur and at the instance of his wife stayed inside and died of snake-bite. And it was here that Sat Guru created this Shabd.
False is friendship with the false and greedy. False is its foundation. 0 Mullah, no one knows where death shall strike. 
A fair used to be held on Basant panchami. This Gurdwara has been maintained by Bhai Natha Singh with great love and affection. The Gurdwara is beautifully built and it is presently being used as a school for the blind. Gurdwara Sahib has been hidden because the people have occupied the land lying around Gurdwara and built houses on it. The tank built by Bhai Natha Singh Ji is adjacent to it. It is present even to day but it is gradually heading towards extinction.
Guru Ji gave two paisas to Bhai Mardana to buy “falsehood” and “truth” from the market. Some people ridiculed Mardana Ji but there was a Karar (a hindu) named Maula who took two paisas and wrote two chits.
On one chit he wrote, “Life is bitter” while on the other chit he wrote, “Death is truth”. Bhai Mardana presented both the chits to Guru Nanak. Guru Ji handed over the two pieces of paper to Hamza Ghaus Ji who after reading the same, pardoned the residents of Sialkot.
Maula Karar remained with Guru Nanak for some time during his travels. According to Guru’s biographies, once Guru Ji went to fetch Maula Karar. Maula Karar, at the instance of his wife, hid himself inside the dark portion of his house and his wife told Guru Ji that he was not at home. Guru Ji came back and a little later it was learnt that Maula Karar had died of snake bite in the darkness
False is friendship with the false and greedy. False is its foundation. O Mullah, no one knows where death shall strike.”
