Chapter: Man makes a vow seeking something other than what has been preordained

The Prophet (ﷺ) forbade vowing and said, "In fact, vowing does not prevent anything, but it makes a miser to spend his property."

The Prophet (ﷺ) 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."
