Ahmed Abu Bakar Said Al-Kaf (Arabic: أحمد أبو بكر سعيد الكاف; born 6 March 1983) is an Omani professional football referee.

[5] On 18 January 2020, Al-Kaf was questioned for several dubious rulings made in the 2020 AFC U-23 Championship Quarter Finals between Saudi Arabia against host, Thailand.

[55] Al-Kaf's ruling was protested by Indonesian netizens, who coined the incorrect mathematical equation "90+6=99" as an inside joke within the football community.

[56][57] The Football Association of Indonesia (PSSI) had sent a complaint letter to FIFA, with executive member Arya Sinulingga stating "[Al-Kaf] extended the adding time just to allow Bahrain to score an equalizer".

[58][59] We affirm its absolute rejection of such out-of-context behavior by a number of fans and some relevant parties, warning of the consequences of these out-of-context behaviors, stressing the commitment of the Omani staff throughout their honorable history to the utmost levels of professionalism and applying the highest levels of transparency, integrity and impartiality in line with international standards.
