Hanif, who was 81, passed away after battling cancer.
In a statement, ICC Chief Executive David Richardson said Hanif was one of the top cricketers of all-time and an idol for many batsmen.
"It's sad to hear of Hanif's death and I'd like to extend my condolences and those of everyone here at the ICC to Hanif's family, which counts so many cricketers in its number. Hanif took batting to great heights and many batsmen drew inspiration from him," Richardson said in a statement.
Hanif, who scored 3,915 runs in 55 Test matches including 12 centuries, is best known for the longest Test innings played.
