سورة An-Nahl ( The Bees ) - الآية 51

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].
