English Translation:
Narrated Ibn 'Umar Radi Allahu Anhu : The Prophet Sallallahu Alaihi Wasallam forbade vowing and said, "In fact, vowing does not prevent anything, but it makes a miser to spend his property."
Sahih Bukhari, Volume 8, Book 77, Number 605:

Narrated Abu Huraira Radi Allahu Anhu : The Prophet Sallallahu Alaihi Wasallam said (that Allah said), "Vowing does not bring to the son of Adam anything I have not already written in his fate, but vowing is imposed on him by way of fore ordainment. Through vowing I make a miser spend of his wealth."
Sahih Bukhari, Volume 8, Book 77, Number 606
