Then he said to the one he knew would survive, “Mention me in the presence of your master.¹” But Satan made him forget to mention Joseph to his master, so he remained in prison for several years.

And he said to the one whom he knew to be saved: "Mention me to your lord (i.e. your king, so as to get me out of the prison)." But Shaitân (Satan) made him forget to mention it to his Lord [or Satan made Yûsuf (Joseph) to forget the remembrance of his Lord (Allâh) as to ask for His Help, instead of others]. So [Yûsuf (Joseph)] stayed in prison a few (more) years.
