Calf Worshippers

 إِنَّ الَّذِينَ اتَّخَذُواْ الْعِجْلَ سَيَنَالُهُمْ غَضَبٌ مِّن رَّبِّهِمْ وَذِلَّةٌ فِي الْحَياةِ الدُّنْيَا وَكَذَلِكَ نَجْزِي الْمُفْتَرِينَ  وَالَّذِينَ عَمِلُواْ السَّيِّئَاتِ ثُمَّ تَابُواْ مِن بَعْدِهَا وَآمَنُواْ إِنَّ رَبَّكَ مِن بَعْدِهَا لَغَفُورٌ رَّحِيمٌ

Certainly, those who took the calf (for worship), wrath from their Lord and humiliation will come upon them in the life of this world. Thus do We recompense those who invent lies. But those who committed evil deeds and then repented afterwards and believed, verily, your Lord after (all) that is indeed Oft-Forgiving, Most Merciful. [al-Araf (7): 152, 153] 

Those who tortured believers by burning them in trenches of fire:

إِنَّ الَّذِينَ فَتَنُوا الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ ثُمَّ لَمْ يَتُوبُوا فَلَهُمْ عَذَابُ جَهَنَّمَ وَلَهُمْ عَذَابُ الْحَرِيقِ

Verily, those who put into trial the believing men and believing women (by torturing them and burning them), and then do not turn in repentance (to Allâh), then they will have the torment of Hell, and they will have the punishment of the burning Fire. [al-Buruj (85): 10] 

Those who believe in Trinity Doctrine

لَّقَدْ كَفَرَ الَّذِينَ قَالُواْ إِنَّ اللّهَ ثَالِثُ ثَلاَثَةٍ وَمَا مِنْ إِلَهٍ إِلاَّ إِلَهٌ وَاحِدٌ وَإِن لَّمْ يَنتَهُواْ عَمَّا يَقُولُونَ لَيَمَسَّنَّ الَّذِينَ كَفَرُواْ مِنْهُمْ عَذَابٌ أَلِيمٌ  أَفَلاَ يَتُوبُونَ إِلَى اللّهِ وَيَسْتَغْفِرُونَهُ وَاللّهُ غَفُورٌ رَّحِيمٌ

Surely, disbelievers are those who said: "Allâh is the third of the three (in a Trinity)." But there is no Iilâh (god) (none who has the right to be worshipped) but One Ilâh (God -Allâh). And if they cease not from what they say, verily, a painful torment will befall on the disbelievers among them. Will they not turn with repentance to Allâh and ask His Forgiveness? For Allâh is Oft-Forgiving, Most Merciful. [al-Maedah (5): 73,74]
