Qur’an is not a book of science. But, to present its basic message, it focuses our attention on different realities, both within our consciousness and in the outside natural phenomena. Modern science has not found any error in Qur’an’s descriptive statements about nature.
Qur’an says that there is no compulsion in religion (2: 256), preach with wisdom (16: 125), be just even with enemies (5: 8) and know that killing a human is like killing humanity (5: 32). Tolerance will come in our society if right education is received.
