What did Ibn 'Abbas (peace be upon him) say when asked about the prostration in Surat Sa`d?
 Narrated Al-Awwam:                     I asked Muhajid regarding the prostration in Surat Sa`d. He said, "Ibn `Abbas was asked the same question and he said, 'Those are they (the prophets) whom Allah had Guided. So follow their guidance." (6.90) Ibn `Abbas used to perform a prostration (on reading this Sura).
