However, he significantly added that it will be known only after the counting of votes.
Reacting sharply to Tamil Nadu BJP President Tamilisai Soundararajan's claim that DMK was known for changing colours and that it was "establishing contacts" with BJP, Stalin hit back asking her to prove the charge and vowed to quit politics if they proved it.
He denied that he has held any meeting with anyone in BJP.
The DMK chief also asked her if she and Prime Minister Narendra Modi will quit politcs if they fail to prove the meeting,
"I condemn the statement made by BJP State President Tamilisai in the morning today and it's nothing new for the BJP to sow confusion whenever they are set to lose.
"It is the DMK which proposed Rahul Gandhi's name for the prime minister's post first and it is I who called PM Modi as sadist, fascist and dictator. The BJP, which could not stand my campaign against them, has stooped to this level," he said.

Referring to his meeting with Telangana Chief Minister K Chandrashekar Rao on Monday, Stalin said that after the meeting "We have categorically said in a statement that it was a courtesy call but certain people with intentions were trying to give new colour to the meeting."
He said unlike the AIADMK and BJP, the DMK would never break any deal behind the screen.
"We are determined to send the ruling BJP government packing home and we are doubly sure to make Rahul Gandhi as Prime Minister," he said.
Earlier in the day, Tamilsai Soundararajan claimed that DMK is meeting all parties in the country without committing to one.
"All of us know that DMK is known for changing colours - one side Rahul Gandhi, one side KCR, one side PM Modi. They are talking with us through somebody. Yes, they are establishing contacts," she told reporters.
Soundararajan added that Stalin's efforts to get close were due to the fact that BJP was going to sweep the Lok Sabha elections single-handedly.
"BJP is all set to win. All poll predictions only point to this. Wherever you go, you come to know that BJP is winning and that is why they want to be in touch with us," she said.
In the morning, Stalin said he did not see the possibility of the formation of a government of the Third Front at the centre but added significantly that it will be known only after the election results.
"I don't see the possibility of a government of a Third Front. It will be known only after the results on May 23," Stalin told reporters.
He said the TRS chief minister was not on a trip to Tamil Nadu for forming fronts but to visit temples. The meeting with him was only as a matter of courtesy.
Asked about Tamilisai Soundararajan's statement whether his meeting with Rao would make any impact, Stalin shot back saying "it only reflects her wishful thinking".
