{So very truly, We did, indeed, send Noah and Abraham [as messengers]. Thus We placed prophethood and the Scripture among their seed} 57:26.

A prophet is only declared a prophet if mentioned in the Quran or in the authentic Sunnah and Buddah is not one of the prophets.

 

Almighty Allah knows best.
