It is possible for the billionaire Jawad karim (co-founder of Youtube) (http://en.wikipedia.org/wiki/Jawed_Karim) or take the example of Jawad Khahai who is the Vice president of Micrososft (http://www.microsoft.com/presspass/exec/jawadk/default.mspx) to be a devout Muslim, but that is US, but here in India one cannot be a devout Muslim and can grow in corporate ladder. Premji's reluctance to show his Muslim identity is a shame to India's secular image. He is simply scared!!!. In this regard it is pertinent to know how EX ceo of HP clarly fiorian (she is not a Muslim) who managed to talk about the greatness of Islamic civilization to Business leaders http://www.hp.com/hpinfo/execteam/speeches/fiorina/minnesota01.html
(see the last two paragrahs and reader get educate yourslef about Muslims and Islam
Leaders need courage to speak truth even in the face of stiff opposition, but Azim premji doesnt know his own roots and he is a Business man. I dont blame him , he is right in his own way
