Tawhid, The Unity of God from the Holy Qur'an

Surah An-Naml, n.27

Say: Praise be to Allah and peace on His servants whom He has chosen: is Allah better, or what they associate (with Him)? (27:59)

Nay, He Who created the heavens and the earth, and sent down for you water from the cloud; then We cause to grow thereby beautiful gardens; it is not possible for you that you should make the trees thereof to grow. Is there a god with Allah? Nay! they are people who deviate.(27:60)

Or, Who made the earth a resting place, and made in it rivers, and raised on it mountains and placed between the two seas a barrier. Is there a god with Allah? Nay! most of them do not know! (27:61)

Or, Who answers the distressed one when he calls upon Him and removes the evil, and He will make you successors in the earth. Is there a god with Allah? Little is it that you mind! (27:62)

Or, Who guides you in utter darkness of the land and the sea, and Who sends the winds as good news before His mercy. Is there a god with Allah? Exalted by Allah above what they associate (with Him) (27:63)

Or, Who originates the creation, then reproduces it and Who gives you sustenance from the heaven and the earth. Is there a god With Allah? Say: Bring your proof if you are truthful (27:64)

Say: No one in the heavens and the earth knows the unseen but Allah; and they do not know when they shall be raised (27:65)
