He also predicted that the Congress, which was routed in the 2014 Modi wave, would do well this time around.
"Modi stands exposed as he has not fulfilled promises he made during the last national elections. So he will definitely not become the Prime Minister again," Singh claimed while speaking to reporters here.
Asked that some Muslim leaders had objected to the Lok Sabha poll schedule as it clashed with Ramzan, Singh said it was a Constitutional necessity that election results had to be declared before May 26.
"Despite this, I pray to the Election Commission (EC) that even if it does not change the election date, make a change in voting time in such a way so that it facilitates voting (among Muslims)," Singh said.
Queried on the brickbats he received on social media for stressing that India place proof of the February 26 air strike on a terror camp in Pakistan's Balakot before the international community, like the US had done after killing terrorist Osama bin Laden, Singh said he was "grateful" to people who trolled him.
Sidestepping a query on why Assembly elections in Jammu and Kashmir were not being held along with national polls nationwide, Singh stated the EC was "free to take a call on it".
"Jyotiraditya Scindia can give an answer to this question. I can't say anything about it," he replied.
