The ruling on one who begins a voluntary prayer and then the call for the obligatory prayer is made

The first message in this episode is one that reached the program from one of the brother listeners. He named himself at the end of his message, saying: Your brother in Allah, Ibn Mas'ud. Our brother has a number of questions, among which is a question that says: If a person begins a voluntary prayer and the call for the obligatory prayer is made while he is performing the voluntary prayer, does he complete his prayer, or does he cut it off to join the obligatory prayer? And if you say to cut off the voluntary prayer, does it become a debt upon him that he must perform after the obligatory prayer, or not? May Allah reward you with good?
Answer: In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send blessings and peace upon the Messenger of Allah, upon his family and his Companions, and upon those who follow his guidance.
As for what follows:
Allah, Exalted and Majestic is He, has prescribed for the Muslim, when he hears the second call, to cut off the prayer he is in and attend to the obligatory prayer. It is established from the Messenger of Allah (peace and blessings be upon him) that he said: When the prayer is called for, there is no prayer except the obligatory one , narrated by Muslim in his Sahih. So when the prayer is called for and the believer is praying, he cuts it off, whether it is the greeting of the mosque or a regular voluntary prayer. He cuts it off and attends to the obligatory prayer, and it is not upon him to make it up afterwards; because it is a voluntary prayer and it is not obligatory for him to make it up, and praise be to Allah. Yes.
The presenter: May Allah reward you with good.
