Musannaf Ibn Abi Shaybah

Hazrat Ata narrates that the Holy Prophet (peace and blessings be upon him) was delivering a sermon when he (peace and blessings be upon him) said to the people: Sit down! Hazrat Abdullah bin Masood (may Allah be pleased with him) heard this. At that time, he was at the door. So he sat down. The Prophet (peace and blessings be upon him) said: O Abdullah! Come inside.

Hazrat Qais narrates that the Holy Prophet (peace and blessings be upon him) was delivering a sermon when my father arrived. He stood in front of the Prophet (peace and blessings be upon him) in the sun. The Prophet (peace and blessings be upon him) gave instructions regarding him, so he was moved to the shade.

Hazrat Aamir says that people used to greet the Imam with salaam while he was on the pulpit. And the Imam would also reply.

Hazrat Ibn Sirin narrates that people used to seek permission from the Imam while the Imam was on the pulpit. Then, when Ziyad was the caliph and this seeking of permission became frequent, Ziyad said: Whoever places his hand on his nose, this will be considered as permission (in his stead).

Hazrat Jabir narrates that Hazrat Sulaik Ghatafani came while the Holy Prophet (peace and blessings be upon him) was delivering the sermon. The Prophet (peace and blessings be upon him) asked him, "Have you offered the prayer?" He replied, "No!" The Prophet (peace and blessings be upon him) said, "Offer two rak‘ahs with brevity." And (Imam) Abu Hanifa's opinion has been mentioned that: The Imam should not converse with anyone during his sermon.
