Use your mind to know the Creator

(60) [More precisely], is He [not best] who created the heavens and the earth and sent down for you rain from the sky, causing to grow thereby gardens of joyful beauty which you could not [otherwise] have grown the trees thereof? Is there a deity with Allah? [No], but they are a people who ascribe equals [to Him].
(61) Is He [not best] who made the earth a stable ground and placed within it rivers and made for it firmly set mountains and placed between the two seas a barrier? Is there a deity with Allah? [No], but most of them do not know.
(62) Is He [not best] who responds to the desperate one when he calls upon Him and removes evil and makes you inheritors of the earth? Is there a deity with Allah? Little do you remember.
(63) Is He [not best] who guides you through the darknesses of the land and sea and who sends the winds as good tidings before His mercy? Is there a deity with Allah? High is Allah above whatever they associate with Him.
(64) Is He [not best] who begins creation and then repeats it and who provides for you from the heaven and earth? Is there a deity with Allah? Say, "Produce your proof, if you should be truthful."
(65) Say, "None in the heavens and earth knows the unseen except Allah, and they do not perceive when they will be resurrected."
(66) Rather, their knowledge is arrested concerning the Hereafter. Rather, they are in doubt about it. Rather, they are, concerning it, blind.
