The ruling on praying between the adhan and the iqamah when there is a lesson in the mosque

Question:
I heard the questioner say: Is it permissible for me to pray two rak'ahs between the adhan and the iqamah, while the Shaykh is delivering his lecture in the mosque? Please advise us, may Allah reward you.

Answer:
Yes, when one enters the mosque, he prays two rak'ahs, even if the imam is delivering the khutbah, even if he is giving a sermon, even during the time of the Friday khutbah, he does not sit until he prays two rak'ahs, even on Friday during the khutbah. When a man entered while the Prophet (peace and blessings be upon him) was delivering the khutbah, he said to him: "Stand up and pray two rak'ahs." He commanded the prayer of greeting the mosque.
