Sir — In the passing away of noted Islamic scholar and social scientist Asghar Ali Engineer in Mumbai on Tuesday, after prolonged illness, the nation has lost a preacher of global peace and communal harmony. Though born in an orthodox Bohra priestly family, Engineer was a true secularist who worked assiduously all his life to promote peace and brotherhood among people of different faiths. He was an advocate of non-violence and communal harmony, for which he was feted and invited to lecture in prestigious forums across the world.
