The Exceed And Excel filly, who won the Group Two Duchess of Cambridge on Newmarket's July course in mid-summer, was last seen in Britain finishing a close-up third to Lezoo in the Cheveley Park on the Rowley Mile course in September.
While she tackled six furlongs exclusively in her two-year-old career on these shores, she was upped in trip with success when shipped to Dubai over the winter.
Mawj duly won the seven-furlong Jumeirah Fillies Classic and then scooted to an eight-and-a-half-length success in the Jumeirah Fillies Guineas on her first try over a mile.
Though not the biggest, she has proven herself to be all heart in winning four of her seven career starts, and she is as short as 12-1 for the mile fillies' Classic.
Bin Suroor said: "She is good, has been working well and in good form. She will run in the Guineas.
"She is a nice filly and a proven filly. She has shown plenty of speed, but she stayed a mile well in Dubai and now we will give her a chance in the Guineas.
"It is a very tough race, but we have to give her a chance and see how she goes, as she has earned that chance.
"She has grown a little, but not much. That is why we gave her a break between races. Two-year-olds, when you give them a break, they generally grow and strengthen."
