Allah says, `He sent Messengers to the nations of the past, and they were
rejected. You, O Muhammad, have an example in your brothers among the
Messengers, so do not be distressed by your people's rejection. As for the
idolators' rejection of the Messengers, the reason for this is that the Shaytan
made their deeds attractive to them.'
[فَهُوَ وَلِيُّهُمُ
الْيَوْمَ]
(So today he (Shaytan) is their helper,) meaning they will be suffering
punishment while Shaytan is their only helper, and he cannot save them, so they
have no one to answer their calls for help, and theirs is a painful
punishment.
