Abu Dhabi police arrested 179 beggars over the course of Ramadan, the force said on Monday.
Officers said the offenders tried to win sympathy by making up stories.
The force also warned of ongoing operations to clamp down on the illegal practice.
Authorities urged people to donate to charity through the official channels to ensure the funds reach those most in need.
Members of the public can report beggars by calling 800 2626, by text at 282 or through email at aman@adpolice.gov.ae.
Dubai Police arrested hundreds of people in an anti-begging campaign during Ramadan and Eid Al Fitr.
A senior officer said the practice was a threat to public safety.
Offenders face fines of up to Dh5,000 ($1,361) and three months in jail.
