Prophet Abraham - 14:35 "Once Abraham said: "My Lord, make this town safe and protect me and my children from serving idols."
What did the people of Prophet Abraham serve?
The Cattle/6:74 "Abraham said to his father Azer: "Do you take statues as gods? I see you and your people in manifest error."
وَاِذْ قَالَ اِبْرٰه۪يمُ لِاَب۪يهِ اٰزَرَ اَتَـتَّخِذُ اَصْنَاماً اٰلِهَةًۚ اِنّ۪ٓي اَرٰيكَ وَقَوْمَكَ ف۪ي ضَلَالٍ مُب۪ينٍ

The Prophets/21:51 We had bestowed on Abraham the gift of understanding and comprehension before, and We knew him well.
وَلَقَدْ اٰتَيْنَٓا اِبْرٰه۪يمَ رُشْدَهُ مِنْ قَبْلُ وَكُنَّا بِه۪ عَالِم۪ينَۚ
The Prophets/21:52 "He said to his father and his people, "What are these statues to which you devote yourselves?"
اِذْ قَالَ لِاَب۪يهِ وَقَوْمِه۪ مَا هٰذِهِ التَّمَاث۪يلُ الَّت۪ٓي اَنْتُمْ لَهَا عَاكِفُونَ
