She said the experience was a humbling one, given that she still does not know who nominated her.
Ms Siddiqui, who set up the Centre for the Study of Islam at the university, said: “In this fractured culture that we live in, this honour bears witness to the importance of inter-religious work.”
She admitted to feeling “chuffed”, adding: “Someone took the time to write a letter and put me forward for an honour. That is something I find very humbling.”
Ms Siddiqui is chairwoman of the BBC’s Scottish Religious Advisory Committee and has advised on a number of legal prosecutions.
