He spent nearly an hour with his relatives amidst tight security at the Ranjit Avenue gurdwara.
Earlier, Singh went to Golden Temple with wife Gursharan Kaur where the two of them spent around 35 minutes, including about 10 minutes inside the sanctum sanctorum.
After paying obeisance, the two went to the information centre of Golden Temple where they were honoured with a set of Sikh religious books, a woolen shawl and a replica of Golden Temple by Shiromani Gurdwara Parbandhak Committee (SGPC) officials.
Gurbachan said Singh and his wife could not spend much time in the sanctum sanctorum since Kaur was suffering from a knee problem and was unable to sit cross-legged for a long time.
State Congress chief Amarinder Singh was also in the city to address a political rally, but he could not meet Singh, the party's district rural chief, Gurjit Singh Aujla, said.
He added that there was no intimation on Singh's visit to any of the party leaders as it was "strictly private".
