Who Was the First Prophet?
Question

I would like to know if Adam -Peace be upon him- was a prophet and if he was not, who was our first prophet? Basically, the origin and the history of Islam.
Praise be to Allah.Adam (peace be upon him) was the first of the Prophets, as it says in the Hadith narrated by Ibn Hibban in his Sahih, that the Prophet (peace and blessings of Allah be upon him) was asked about Adam – was he a Prophet? He said, “Yes, a Prophet to whom Allah spoke.” But he was not a Messenger, because of the Hadith about intercession in which it says that the people will go to Nuh (peace be upon him) and say to him, “You are the first Messenger whom Allah sent to the earth.” 
This text clearly indicates that Nuh (peace be upon him) was the first of the Messengers. And Allah knows best.” (Majmu` Fatawa Ibn `Uthaymin, 1/317)
Adam, the father of mankind, was a Prophet, so he was the first of the Prophets.
