Hazrat Sufyan bin Husain narrates that I was with Hazrat Hasan when he recited the verse of prostration from Surah Sad and then performed prostration.

Hazrat Masrooq used to perform sajdah (prostration) in Surah Saad.

Hazrat Abu Abdur Rahman used to perform sajdah in Surah Sad.

Hazrat Saeed bin Jubair states that I saw Hazrat Dahhak bin Qais performing sajdah in Surah Saad, so I mentioned this to Hazrat Ibn Abbas (may Allah be pleased with them). He said that he had seen Hazrat Umar bin Khattab performing sajdah in Surah Saad.

Hazrat Ibn Abbas (may Allah be pleased with them both) says that there is a prostration (sajdah) in Surah Sad. Then he recited this verse { أُولَئِکَ الَّذِینَ ہَدَی اللَّہُ فَبِہُدَاہُمُ اقْتَدِہِ }
