What is the ruling on one who made a covenant with Allah to complete the recitation of the Qur’an once every month, then forgot this covenant for a long time? Is there an expiation due for the past days, and what is its amount? Is he obligated to fulfill this covenant for the rest of his life? And what should he do if he finishes the recitation before the end of the month?

A Muslim should be cautious about making covenants with Allah, as they are not to be taken lightly. Whoever makes a covenant with Allah to do something must fulfill it; otherwise, they may face punishment, as stated in the Almighty's words: (And fulfill the covenant; indeed, the covenant will be questioned). A covenant takes the ruling of a vow (nadhr) if its intention is to obligate oneself to an act of obedience or an act of drawing closer to Allah, such as: "I covenant with Allah that I will pray two rak'ahs." However, if the intention is to prevent or encourage something and not an act of drawing closer, it takes the ruling of an oath (yameen). A vow of obedience must be fulfilled. Whoever vows to complete the Quran every month but fails to do so in some months must make up for those missed completions. In addition to making up for them, they must offer an expiation for an oath (kaffarat yameen) for each month they failed to fulfill their vow. If they are unable to provide the expiation, they must fast for three days. A vow made with "every month" implies continuity and permanence, and it must be fulfilled for life. The month is calculated from the time the vow was made.
