Vowing to do one of two things if he ever masturbates again

Q: I am a twenty-six-year-old man. I am married, praise be to Allah, and I have a little girl. When I was fifteen or sixteen years old, I felt powerful lust that I could not restrain except by masturbation, which increased my worries. One day, I made a vow to observe Sawm (fasting) for two consecutive months if I masturbate again. However, I did it again the following day. Now, and after nine years have passed, I would like to know whether I have to fulfill my vow. It is so difficult for me to observe Sawm for two consecutive months under my current work circumstances. However, if you tell me that I have to do so, I will do my best to fulfill my vow, in order to apply Allah's saying, They (are those who) fulfil (their) vows, and they fear a Day whose evil will be wide-spreading.

A: First, masturbation is Haram (prohibited).Second, you have to fulfill your vow, as Allah has praised those who fulfill their vows (Part No. 23; Page No. 283) in His saying, They (are those who) fulfil (their) vows It was also authentically reported from the Prophet (peace be upon him) that he said, A person who vows to do an act of obedience to Allah should do so. If a person vows to quit a sin, this is considered a form of obedience.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
