The consultation on the new 650-pupil west end non-denominational school attracted one of the biggest responses, with 435 from "friends of Willowbank" supporting its establishment as a Muslim school; 78 of those were from outwith Glasgow.
Concerns from parents in other west end schools included fears that the new school would be too big. The city-wide Save our Schools campaign accused the council of creating "impersonal superschools which nobody wants".
As a concession, the council agreed to hold a further consultation on allowing greater flexibility for catchment areas in the west end. However, Margaret McCafferty, convener of Glasgow's education committee, said the council did not consider the size of the school would cause difficulties.
"It will not be much larger than the roll of Hillhead primary school was some eight years ago, and indeed will be considerably smaller than the 800-plus capacity of one of the country's most successful primaries in neighbouring East Renfrewshire," Mrs McCafferty said.
