Musannaf Ibn Abi Shaybah

Hazrat Abu Qilabah and Hazrat Ibn Sirin, after reciting the verse of prostration and performing the prostration, would say the salam.

When Hazrat Abu Abdur Rahman would recite a verse of prostration, after performing the prostration he would say "Assalamu Alaikum" and turn to offer salam.

Hazrat Hakam says that I saw Hazrat Ahwas recite the verse of prostration, and after performing the prostration, he turned his head to the right once to say salam.
