Singh had met Shah in Delhi last month fuelling speculations that he may switch over to the saffron camp.
The veteran leader and Rajya Sabha MP, who has openly revolted against Chief Minister Bhupinder Singh Hooda and was removed from the party's working committee last month, however, said that he has so far not quit the Congress.
The Jind rally is being organised by Yuva Shakti, a youth organisation started by the supporters of Singh.
He said that there were some leaders in the Congress camp, including former Union Minister Kumari Selja, who felt that the party would reach out to him.

"I have clearly said that stage has crossed. That stage is over now. I am now focusing on the rally," he said.
Hitting out at Hooda, Singh said, "Congress in Haryana is no longer the party it used to be. It has now become Hooda's Congress."
He alleged that Hooda had centralised powers and it was one of the reason why the Congress had fared poor in the Lok Sabha polls. Congress managed to win only one seat out of total ten LS seats in the state.
"I had demanded that Hooda should be changed so that Congress's prospects in the polls could improve, but that did not happen... Now I am not going to contest future election on Congress symbol," he said.
A prominent leader from Haryana's Banger area, he has over the past one year openly criticised Hooda from several platforms for alleged lopsided development.
