[Satan] said, "Because You have put me in error, I will surely sit in wait for them [i.e., mankind] on Your straight path.
Brief commentary
Satan said: 'Because You have made me fall into error through not following Your command to bow down to Adam, I will surely sit in wait for the children of Adam upon Your straight path, to turn them away and mislead them from it, just as I was misled through not bowing down to Adam.'
