While you are Samidun.
Sufyan Ath-Thawri reported that his father narrated that Ibn Abbas said about Samidun,
"Singing; in Yemenite dialect `Ismidfor us' means `Sing for us."'
Ikrimah said something similar.
In another narration from Ibn Abbas, he said that,
(Samidun) means, "Turning away."
Similar was reported from Mujahid and Ikrimah.
Allah the Exalted ordered His servants to prostrate to Him, worship Him according to the way of His Messenger, and to fulfill the requirement of Tawhid and sincerity,
فَاسْجُدُوا لِلَّهِ وَاعْبُدُوا
