Mr. Sani, who until his death represented Mashi/Dvisi Federal Constituency on the platform of the All Progressives Congress, died Wednesday morning.
He was 51.
Speaker Yakubu Dogara on Wednesday mourned the passing of the lawmaker.
“Our late colleague was humane, principled and a cosmopolitan who interacted freely with all members,” the Speaker said in a statement while condoling with his family.
Mr. Sani is the second lawmaker to die in office within the last one year, coming months after Adewale Oluwatayo from Lagos State died in Abuja.
