What is the ruling on one who vowed to pray one hundred rak'ahs daily and is unable to fulfill it?

Question : The questioner says that his mother made a vow to Allah to pray one hundred rak'ahs a day. Is she required to do anything if she does not fulfill her vow because she is unable to?

Answer : First, may Allah bless you. I inform you that our Prophet Muhammad (peace and blessings be upon him) forbade vows. . . And he said, Be aware, the Messenger (may Allah's prayers and peace be upon him) is the most perfect of creation in giving sincere advice to the Ummah. Do you agree with this? Good. How is that?
A person says, "If such and such happens, I have a vow to Allah to give one hundred riyals in charity." He does not give the one hundred riyals as charity except for the sake of the vow. And a person says, if he has a sick person or he is chronically ill, "If I am healed, or if Allah heals my sick person, I have a vow to Allah." He thinks that the vow will heal the sick person. But the vow does not avert divine decree. If Allah has decreed that this sick person will die, he will die; or if He has decreed that his illness will increase, his illness will increase. The vow has no effect.
However, a vow is a burden on the person. How many people have vowed for something, and that thing happened, and then they went to the door of the scholars seeking to get rid of what they vowed. This is part of the question you just heard. Also, some young people have a difficult subject, like... what? English, according to your speech, and others, and the sciences, mathematics, physics, chemistry, and the like. In any case, the student loses hope of success and says, "I have a vow to Allah that if I succeed, I will fast for a month." Then Allah decrees that he succeeds. He is not in the state of the vow, but Allah has decreed this. So when he succeeds, the vow holds him. He goes to the scholars asking, "What do you say?" Because... what? He wants to get rid of it. But he has made a condition with his Lord and pledged to his Lord that if such and such happens, he will perform the fasting. So he is obligated to fulfill what he vowed. If he does not do so, listen, Allah the Exalted said, We have a condition and a conditioned one. "If He gives us from His bounty, this is the conditioned condition: we will surely give charity and we will surely be among the righteous." When He gave them from His bounty, they turned away and did not give charity, and they were not righteous.
The result is We ask Allah for well-being. This matter is serious. We say regarding this woman: since she vowed to fast one hundred days, she must seek help from Allah and fast... what? She must pray one hundred rak'ahs a day. She must seek help from Allah and pray. And she must be tranquil. Trust that if she prays one hundred rak'ahs with tranquility, how much is left? One hundred rak'ahs with tranquility, each rak'ah is ten minutes. One hundred times ten is one thousand minutes. One thousand minutes will take up a lot of the day. But she is the one who did this to herself. She is the one who did this to herself. So she must seek help from Allah and pray what she vowed, and she must strive to be tranquil. If she is unable, if she is unable, the vow becomes like an obligatory duty by the original law. If a person is unable to do it, it is dropped, because it is from the established and known rule in the Shari'ah that there is no obligatory... what? There is no obligatory duty with inability. As He the Exalted said, and His saying, But it is good for her to feed ten poor people due to her not fulfilling the vow.
