It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whatever Allah Almighty has not decreed, the vow of the son of Adam cannot bring it to him. However, through this vow, money is extracted from a miserly person; by making a vow, he gives something which he would never give in his state of miserliness.
