"The match officials' report, which was handed over to the Pakistan team manager Moin Khan, cited concerns about the legality of the 34-year-old's bowling action," the ICC said.
Pakistan won the match by 248 runs to take a 1-0 lead in the three-match series.
Hafeez's bowling action will now be scrutinised further under the ICC process relating to suspected illegal bowling actions reported in Tests, one-day matches and T20Is.
As per the ICC rules on dealing with the suspect action, Hafeez is required to undergo testing within 21 days, and, during this period, Hafeez is permitted to continue bowling in international cricket until the results of the testing are known.
Hafeez is the second Pakistani behind Saeed Ajmal, also an off-spinner, to be reported in a major crackdown on bowlers with suspect actions the ICC launched in June this year.
Besides Ajmal, Sri Lanka's Sachitra Senanayake, New Zealand's Kane Williamson, Bangladesh's Sohag Gazi and Zimbabwe's Prosper Utseya - all off-spinners - were reported and subsequently suspended to allow remedial work on their actions.
Zimbabwe match referee Andy Pycrot was the common official in both the Ajmal and Hafez cases.
He was also the match referee when Ajmal was reported during the Galle Test against Sri Lanka in August this year.
The on-field umpires in the Abu Dhabi Tests were Sri Lanka's Ranmore Martinesz and Rod Tucker of Australia while the tv umpire was Paul Reiffel, also from Australia.
Ajmal is currently in England to have an unofficial reassessment on his remodelled action and if it is found to be within the allowed limits of a 15 degree elbow extension, then Pakistan Cricket Board (PCB) will apply for an official reassessment with the ICC.
Hafeez's action was also reported during a Twenty20 league in India in September this year, but the PCB said the bowler did some remedial work in the national cricket academy in Lahore.
He was not reported during the 2-0 win over Australia which finished last week.
Hafeez's action was cleared after being reported in a one-day match against the West Indies in Brisbane in 2005.
Before the Australia series Hafeez said he has been bowling with the same action for 11 years.
"Look, I have not changed my action. It's the same for 11 years now, so I am confident and have no worries over my action," said Hafeez last month.

Hafeez will be fine .. and ajmal will be back too !
can't play them, ban them.
I was closely watching his action during these 2 test matches and really i don't feel there is some thing wrong with his action. On the other hand, Ajmal has a clear bend. These umpires now adays are going crazy and soon they will be calling leg spinners action illegal as well LOL.
This is a conspiracy against Pakistan!. Guess who is the chairman of the ICC?
Are you kidding us @ Waseem Sarwar that ICC (Indian Cricket Council) will every give it a slightest thought about looking at Ashwin's action even if his elbow flexes up to 90 degrees?
If something was wrong with his action, he should have been reported against Aussies but rules are rules. He should get his action tested and corrected if needed. I would love to see results of Ashwin's bowling if ICC ever reports him because he does have a pretty obvious bend while he is bowling off spin.
