Referring to the 2008 attack at Ahmedabad civil hospital, Modi said, "should not those sitting in Delhi at that time have taught those sitting in Pakistan a lesson."
Earlier, he exuded confidence of his party (BJP) returning to power in the 2019 Lok Sabha elections. "Don't worry... I am coming back in 2019 so if you need anything from the Central government, you can tell me," he told a gathering of the Patidar community at Jaspur near here.
The Prime Minister was speaking at the foundation stone-laying ceremony of the Rs 1,000 crore Umiya Mata Temple complex of the community on the outskirts of Ahmedabad.
Wishing all success to the trustees of Umiya Mata Foundation for this project, Modi said, amid huge applause, "If you need anything in this, my home in New Delhi is all yours, and don't worry I am there even after 2019 (elections)".
