Book 001, Number 0019:
It is narrated on the authority of ('Abdullah) son of 'Umar, that the Holy Prophet (may peace of Allah be upon him) said: (The superstructure of) al-Islam is raised on five (pillars), i. e. Allah (alone) should be worshipped, and (all other gods) beside Him should be (categorically) denied. Establishment of prayer, the payment of Zakat, Pilgrimage to the House, and the fast of Ramadan (are the other obligatory acts besides the belief in the oneness of Allah and denial of all other gods).
About the Shahadah:
2:163- And you god is One God. There is no deity [worthy of worship] except Him, the Entirely Merciful, the Especially Merciful.
4:87-Allah-there is no deity except Him....
5:73- They have certainly disbelieved who say, "Allah is the third of three (trinity). And there is no god except One God.....
6:102- That is Allah, your Lord; there is no deity except Him, the Creator of All things, so worship Him. And He is Disposer of all things.
6:106- Follow, (O Muhammad

), what has been revealed to you from your Lord-there is no deity except Him-and turn away from those who associate others with Allah.
9:31-They have taken their scholars and monks as lords besides Allah, and [also] the Messiah, the son of Mary. And they were not commanded except to worship One God; there is no deity except Him. Exalted is He above whatever they associate with Him.
There is a lot more for shahadah, just look in the index of your Qur'an and they should give it to you.
Here's some more:
Book 001, Number 0004:
Abu Huraira reported: One day the Messenger of Allah (may peace be upon him) appeared before the public that a man came to him and said: Prophet of Allah, (tell me) what is Iman. Upon this he (the Holy Prophet) replied: That you affirm your faith in Allah, His angels, His Books, His meeting, His Messengers and that you affirm your faith in the Resurrection hereafter. He (again) said: Messenger of Allah, (tell me) what does al-Islam signify. He (the Holy Prophet) replied: Al-Islam signifies that you worship Allah and do not associate anything with Him and you establish obligatory prayer and you pay the obligatory poor-rate (Zakat) and you observe the fast of Ramadan. He (the inquirer) again said: Messenger of Allah, what does al-Ihsan imply? He (the Holy Prophet) replied: That you worship Allah as if you are seeing Him, and in case you fail to see Him, then observe prayer (with this idea in your mind) that (at least) He is seeing you. He (the inquirer ) again said: Messenger of Allah, when would there be the hour (of Doom)? He (the Holy Prophet) replied: The one who is asked about it is no better informed than the inquirer. I, however, narrate some of its signs (and these are): when the slave-girl will give birth to he master, when the naked, barefooted would become the chiefs of the people - these are some of the signs of (Doom). (Moreover) when the shepherds of the black (camels) would exult themselves in buildings, this is one of the signs of (Doom). (Doom) is one of the five (happenings wrapped in the unseen) which no one knows but Allah. Then he (the Messenger of Allah) recited (the verse):" Verily Allah! with Him alone is the knowledge of the hour and He it is Who sends (down the rain) and knows that which is in the wombs and no person knows whatsoever he shall earn tomorrow, and a person knows not in whatsoever land he shall die. Verily Allah is Knowing, Aware. He (the narrator, Abu Huraira) said: Then the person turned back and went away. The Messenger of Allah (may peace be upon him) said: Bring that man back to me. They (the Companions of the Holy Prophet present there) went to bring him back, but they saw nothing there. Upon this the Messenger of Allah remarked: he was Gabriel, who came to teach the people their religion.
Book 001, Number 0033:
It has been narrated on the authority of Abdullah b. 'Umar that the Messenger of Allah said: I have been commanded to fight against people till they testify that there is no god but Allah, that Muhammad is the messenger of Allah, and they establish prayer, and pay Zakat and if they do it, their blood and property are guaranteed protection on my behalf except when justified by law, and their affairs rest with Allah.
InshaAllah I hope I have helped you and May Allah protect our hearts from deviating from Islam. Ameen.
