"The Congress is being rejected from every corner of the country. They need to introspect," Modi said at a rally here.
Making a veiled reference to Gandhi, he said, "One leader during his speech said Modi gave 48,000 crore acres of land to an industrialist. The area he is talking about is three times the size of land available on the earth. I don't know what to do... to laugh or cry."
Gandhi had during one of his rallies in Gujarat alleged that Modi had given a vast tract of land to an industrialist in Mundra of Kutch district.

Referring to the meme tweeted by the Youth Congress, Modi said the Congress was using abusive language against him.
"It is their 'sanskar' (values). I have not studied in an English medium school but in a government school where they taught me how to lead life," Modi said in Surandranagar.
He also accused the Congress of spreading poison of casteism to win elections in the state.
"They know that they have no chance, so they are spreading the poison of casteism to win in the state. They have done it earlier. Now they are doing it again," Modi said.
