Ruba'iyat By ALLAMA IQBAL:

Faith is like Abraham at the stake: to be

Self-honoring and God-drunk, is faith. Hear me,

You whom this age's way so captivate!

To have no faith is worse than slavery.

Here Iqbal aims at enriching our faith like that of Abraham, who remained constant and consistent. Muslim harmony depends upon the same sort of faith. To Iqbal, absence of faith means an object life, even worse than slavery.
