There has already been for you an excellent example

[Abu Dujanah]

قَدْ كَانَتْ لَكُمْ أُسْوَةٌ حَسَنَةٌ فِي إِبْرَاهِيمَ وَالَّذِينَ مَعَهُ إِذْ قَالُوا لِقَوْمِهِمْ إِنَّا بُرَاء مِنكُمْ وَمِمَّا تَعْبُدُونَ مِن دُونِ اللَّهِ كَفَرْنَا بِكُمْ وَبَدَا بَيْنَنَا وَبَيْنَكُمُ الْعَدَاوَةُ وَالْبَغْضَاء أَبَداً حَتَّى تُؤْمِنُوا بِاللَّهِ وَحْدَهُ إِلَّا قَوْلَ إِبْرَاهِيمَ لِأَبِيهِ لَأَسْتَغْفِرَنَّ لَكَ وَمَا أَمْلِكُ لَكَ مِنَ اللَّهِ مِن شَيْءٍ رَّبَّنَا عَلَيْكَ تَوَكَّلْنَا وَإِلَيْكَ أَنَبْنَا وَإِلَيْكَ الْمَصِيرُ

Allaah, Jalla wa 3alaa, Says (~translation of meaning):

{There has already been for you an excellent example to be followed in Ibraaheem and those with him, when they said to their people, "Indeed we are disassociated from you and from whatever you worship other than Allaah. We have rejected you, and there has started between us and you animosity and hatred forever until you believe in Allaah alone."} (al-Mumtahinah v. 4)
