It is staded as follows in the 164th verse of Surat al-Baqarah that one of the purposes of the Qur'an's revelation is to invite people to think: "In the creation of the heavens and earth and the alternation of the night and day the water which sail the seas to people's benefit and the water which Allah send down from the sky-by which He brigs the earth to life when it was dead and scatters about in it creatures of every kind -and the varying direction of the winds and the clouds subservient between heaven and earth there are sings for people who use their intellect."Hundreds of similar verses in the Qur'an summon people to think on those beings that are created.
