Worshipping Auliya Besides Allah

إِنَّا أَنزَلْنَا إِلَيْكَ الْكِتَابَ بِالْحَقِّ فَاعْبُدْ اللَّهَ مُخْلِصًا لَهُ الدِّينَ (الزمر: 2).
أَلاَ لِلَّهِ الدِّينُ الْخَالِصُ وَالَّذِينَ اتَّخَذُوا مِنْ دُونِهِ أَوْلِيَاءَ مَا نَعْبُدُهُمْ إِلاَّ لِيُقَرِّبُونَا إِلَى اللَّهِ زُلْفَى إِنَّ اللَّهَ يَحْكُمُ بَيْنَهُمْ فِي مَا هُمْ فِيهِ يَخْتَلِفُونَ إِنَّ اللَّهَ لاَ
يَهْدِي مَنْ هُوَ كَاذِبٌ كَفَّارٌ
(الزمر: 3)

2. Verily, We have sent down the Book to you (O Muhammad ) in truth: So worship Allah (Alone) by doing religious deeds sincerely for Allah's sake only, (and not to show-off, and not to set up rivals with Him in worship).

3. Surely, the religion (i.e. the worship and the obedience) is for Allah only. And those who take Auliya' (protectors and helpers) besides Him (say): "We worship them only that they may bring us near to Allah." Verily, Allah will judge between them concerning that wherein they differ. Truly, Allah guides not him who is a liar, and a disbeliever.
