Explanation of the author's statement: "The second is the vow of contention and anger, which is attaching one's vow to a condition intended to prevent it, or to compel it, or to affirm it, or to deny it"

The Shaykh : The second is the vow of contention and anger. This type of vow falls under the category of attributing a thing to its cause; that is, a vow whose cause is contention, meaning dispute, quarrel, or something similar. Anger is self-evident; it is the boiling of the blood in the heart and the surging of blood, which causes a person to become agitated and make a vow. But what is its definition? He said: "It is attaching one's vow to a condition intended to prevent it, or to compel it, or to affirm it, or to deny it". This means that a person attaches his vow to a condition with the intention of preventing it. For example, he might say, "If I do such-and-such, I have a vow to Allah to fast for a year." What is his purpose with this? His purpose is to prevent himself from doing it, because if he remembers the year of fasting, he will refrain. Is that clear? Or a person might say to someone he is trying to deter by an oath, for example addressing his son, "If you do such-and-such, I have a vow to Allah to fast for a year." This is also called a vow of what? Contention and anger. It is called the vow of contention and anger. The intention behind it is prevention, right? Good. Or it is to compel it, which is the opposite of preventing it; that is, he makes a vow to compel himself to perform an act. For example, he might say, "If I do not do such-and-such, my slaves are free, my property is an endowment, and my money is a gift." Ah, everything is settled. Good, this man says.
