Allah says: `What We have commanded you to do is part of good manners, and what We have forbidden you are evil qualities. We have revealed this to you, O Muhammad, so that you may command the people likewise.'

﴿وَلاَ تَجْعَلْ مَعَ اللَّهِ إِلَـهًا ءَاخَرَ فَتُلْقَى فِى جَهَنَّمَ مَلُومًا﴾

(And set not up with Allah any other god lest you should be thrown into Hell, blameworthy) meaning, your own self will blame you, as will Allah and His creation.

﴿مَّدْحُورًا﴾

(rejected) means far removed from everything good. Ibn `Abbas and Qatadah said: "(It means) cast out.'' This is an address to the Ummah via the Messenger , for he is infallible.

﴿أَفَأَصْفَـكُمْ رَبُّكُم بِالْبَنِينَ وَاتَّخَذَ مِنَ الْمَلَـئِكَةِ إِنَاثًا إِنَّكُمْ لَتَقُولُونَ قَوْلاً عَظِيمًا ﴾

(40. Has then your Lord preferred for you sons, and taken for Himself from among the angels daughters Verily, you indeed utter an awful saying.)
