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.)
