Oaths and Vows
Chapter: To fulfil one's vow
Narrated Abu Huraira:
The Prophet (ﷺ) said, "Allah says, 'The vow, does not bring about for the son of Adam anything I have not decreed for him, but his vow may coincide with what has been decided for him, and by this way I cause a miser to spend of his wealth. So he gives Me (spends in charity) for the fulfillment of what has been decreed for him what he would not give Me before but for his vow."
