Gero, who spoke on Monday, in Asaba, was reacting to the recent bomb blasts in Yobe and Borno.
He condemned the blasts, noting that Islam is holy.
Gero described the killings as barbaric and man's inhumanity to man, saying that the Eid-el-Kabir was a time to show love among Muslims.
He urged religious tolerance between Muslims and Christians, stressing that the two religions were the same.
The community leader pledged the support of the Hausa to the realisation of the goals of the present administration in the country.
Meanwhile, some Muslim faithful in Asaba have resumed business on a skeletal scale.
Some of them said that the Eid-el-Kabir was on Sunday, arguing that there was no point for them to stay at home.
The Federal Government declared Nov. 7 and Nov. 8 as public holidays to mark the Eid-el-Kabir
