It is wrong to label successful Indians by religion and start analyzing their Muslimness. We saw this with Pres Kalam when some people despite his open indifference to Islam were clamoring to make a Muslim out of him. Premji would be in the same category. Its only celebrities like SRK or AR Rahman who even wear Islam on their sleeves. Chances are with little Hindu openness these gentlemen would have completely aligned with Hinduism.
