Surah Al Imran
Allah then said, وَلاَ يَأْمُرَكُمْ أَن تَتَّخِذُواْ الْمَلَـئِكَةَ وَالنَّبِيِّيْنَ أَرْبَابًا (Nor would he order you to take angels and Prophets for lords.) The Prophet does not command worshipping other than Allah, whether a sent Messenger or an angel. أَيَأْمُرُكُم بِالْكُفْرِ بَعْدَ إِذْ أَنتُم مُّسْلِمُونَ (Would he order you to disbelieve after you have submitted to Allah's will) meaning, he would not do that, for whoever calls to worshipping other than Allah, will have called to Kufr. The Prophets only call to Iman which commands worshipping Allah Alone without partners. Allah said in other Ayat, وَمَآ أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍ إِلاَّ نُوحِى إِلَيْهِ أَنَّهُ لا إِلَـهَ إِلاَّ أَنَاْ فَاعْبُدُونِ (And We did not send any Messenger before you (O Muhammad ) but We revealed to him (saying): "None has the right to be worshipped but I, so worship Me".) 21:25, وَلَقَدْ بَعَثْنَا فِى كُلِّ أُمَّةٍ رَّسُولاً أَنِ اعْبُدُواْ اللَّهَ وَاجْتَنِبُواْ الْطَّـغُوتَ ...
