Allah Is One

Yet there are men who take (for worship) others besides Allah, as equal (with Allah)
They love them as they should love Allah. But those of Faith are overflowing in their
love for Allah. If only the unrighteous could see, behold, they would see the penalty
that to Allah belongs all power, and Allah will strongly enforce the penalty.
Then would those who are followed clear themselves of those who follow (them) They would
see the penalty, and all relations between them would be cut off.And those who
followed would say: "If only We had one more chance, We would clear ourselves of them, as
they have cleared themselves of us." Thus will Allah show them (The fruits of) their deeds
as (nothing but) regrets. Nor will there be a way for them out of the Fire.

(Surah Baqrah) {Verse No.165 To 167}
