Islam and its practices (prayer, pilgrimage, fasting, etc.) begin with Prophet Abraham:

The Pilgrimage/22:78
And strive and strive hard for the sake of Allah. It is He who has chosen you. He has not made this religion, which is the way of your father Abraham, difficult and burdensome for you. It is He Who has called you Muslims (Muslims) before and now, so that the Messenger may be a witness to you and you may be a witness to the people. Observe the prayer and pay the zakat and cling to Allah; He is your Owner. How good the Owner and how good the Helper!

These are some of the prophets whom Allah has blessed. From the descendants of Adam, from those whom We carried with Noah, from the descendants of Abraham and Israel.
