Standing for the Khutbah after the Iqamah until the Imam bows

Question:
He says: Honorable Shaykh, may Allah grant you success. Some people say that when the prayer is established, they stand and talk until the Imam bows. What is the ruling on doing that?

Answer:
This is not permissible. This is not permissible. He missed the standing, and standing is a pillar of the prayer. If he missed the standing without an excuse, he is the one who was negligent, and his prayer is invalid. He will have missed a rak'ah, which he must perform after the Imam’s taslim, because he missed the standing, which is a pillar of the prayer, without an excuse. However, if he arrived late and the Imam did not wait for him, and he caught the bowing, he bows with him, and he is considered to have caught the bowing, because he is excused.
