Translation of the verse 51 from Surah An-Nahl : Number of verses 128 - - page 272 - Part 14.
And Allah said (O mankind!): "Take not ilahain (two gods in worship, etc.). Verily, He (Allah) is (the) only One Ilah (God). Then, fear Me (Allah) much [and Me (Alone), i.e. be away from all kinds of sins and evil deeds that Allah has forbidden and do all that Allah has ordained and worship none but Allah].
And Allah has said, "Do not take for yourselves two deities. He is but one God, so fear only Me."
(16:51) Allah has enjoined: "You shall not take to yourselves two gods; *43 for He is the only One God: so fear Me."
*43) Negation of two gods by itself negates the existence of more than two gods.
