Tambuwal spoke in Sokoto at a reception which the state government organised in honour of Aliyu Wamakko, his predecessor.
Wamakko was also among the 12 recipients of the 2016 Sheikh Abdullahi Fodio Merit Award organised by the Gwandu Emirate Council of Kebbi state.
“The president has succeeded in tackling the problem of insurgency in the north-east while other security challenges are receiving the necessary attention,” he said.
“The once dreadful Sambisa forest has now been cleared of insurgents and the happy story goes on.
“President Buhari is also doing his best to doggedly fight corruption, diversify the economy and reduce poverty and unemployment.
“The president therefore needs the support and fervent prayers of all Nigerians, irrespective of creed, religion or ethnicity.”
Tambuwal extolled the invaluable contributions of the five former governors of the defunct new PDP, saying their efforts saved democracy.
He said the efforts led to the merger of the legacy political parties that culminated in the formation of the All Progressives Congress (APC).
“That singular patriotic and bold move greatly helped in salvaging Nigeria sequel to the election of President Buhari,” he said.
“Nigerians will not in anyway regret reposing tremendous confidence in the APC at all levels.”
He said the award was for the entire people of the state, noting that “Wamakko is a father to all and he is worthy of emulation”.
Tambuwal commended the Gwandu Emirate Council for the gesture, urging Wamakko not to be complacent.
Also speaking, Murtala Nyako, a former governor of Adamawa, commended the existing cordial relationship between Wamakko and his successor.
“I am urging leaders at all levels to emulate the duo for peace, unity and progress of the country,” he said.
“Fervent prayers should also be sustained for the president and the nation at large.”
Responding, Wamakko dedicated the award to Tambuwal and the people of the state.
“We will continue to strive to defend the dignity and honour of the APC, Sokoto state, Sultanate Council of Sokoto and Nigeria.
“The award will spur me to do more and let me caution political smugglers in the state that my existing relationship with Tambuwal remains solid and cordial.
“We will continue to shame the doubting Thomases, APC in the state is one and all acts of sabotage from within and without would amount to naught.”
