Tinubu, in a statement on Monday, said Sule's death came at a time the nation is in dire need of wise counsel on how to navigate through potential landmines.
Mr Sule was said to have breathed his last in the early hours of Monday at a hospital in Cairo, Egypt.
He also said the deceased, also known by his traditional title as "Danmasanin Kano" was a patriot who espoused the God-given strengths and positive attributes of all the constituent ethnicities in the country.
The Commissioner announced that the Kano State Governor, Alhaji Abdullahi Umar Ganduje has declared Tuesday a work-free day in the state to mourn the death of the elder statesman.
The statement said further confirmed that "he death has occurred today of Alhaji (Dr.) Yusuf Maitama Sule, Dan Masanin Kano".

The Acting President observed that Alhaji Sule, a great Nigerian leader and committed nationalist, positioned himself as an agent of unity.
While at the UN, he chaired the United Nations Standing Committee Against Apartheid then ravaging South Africa.
Tinubu said the consolation, however, was that Sule lived to a ripe age, and in his lifetime, made an indelible mark as a politician, diplomat and statesman. His prayer is that Allah will bless his memory, grant the family and all of us Nigerians the fortitude to bear the irreparable loss.
