We may think of science as one wing and religion as the other; a bird needs two wings for flight, one alone would be useless. Any religion that contradicts science or that is opposed to it, is only ignorance—for ignorance is the opposite of knowledge.

Religion which consists only of rites and ceremonies of prejudice is not the truth. Let us earnestly endeavour to be the means of uniting religion and science.

‘Alí, the son-in-law of Muhammad, said: ‘That which is in conformity with science is also in conformity with religion’. Whatever the intelligence of man cannot understand, religion ought not to accept. Religion and science walk hand in hand, and any religion contrary to science is not the truth.
