Two Kinds of Imam are mentioned in the Holy Quran: the Imams 
who call to Allah and the Imams who call to Fire
2 Aḥadīth
Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from ‘Abdallah ibn Ghalib from Jabir from abu Ja‘far who has said the following. “When the following verse of the Holy Quran was revealed, “On the day when We call every nation with their leaders, (Imams) . .” (7:7), people asked the Holy Prophet (s.a.), ‘Are you not the Imam of all the people altogether?’ The Holy Prophet (s.a.) said, “I am the Messenger of Allah to all the people but after me there will the Imams for the people from my family. They will rise among the people but they will be rejected. The leaders of the unbelievers and misguidance and their followers will do injustice to them. Those who support, love, follow and acknowledge their authority they are from me, with me and will meet me. Let it be known that those who would do injustice to the Imams and reject them they are not from me and with me. I denounce them and all associations with them.”
مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ عَبْدِ الله بْنِ غَالِبٍ عَنْ جَابِرٍ عَنْ ابي جعفر قَالَ قَالَ لَمَّا نَزَلَتْ هَذِهِ الايَةُ يَوْمَ نَدْعُوا كُلَّ أُناسٍ بِإِمامِهِمْ قَالَ الْمُسْلِمُونَ يَا رَسُولَ الله أَ لَسْتَ إِمَامَ النَّاسِ كُلِّهِمْ أَجْمَعِينَ قَالَ فَقَالَ رَسُولُ الله ﷺ أَنَا رَسُولُ الله إِلَى النَّاسِ أَجْمَعِينَ وَلَكِنْ سَيَكُونُ مِنْ بَعْدِي أَئِمَّةٌ عَلَى النَّاسِ مِنَ الله مِنْ أَهْلِ بَيْتِي يَقُومُونَ فِي النَّاسِ فَيُكَذَّبُونَ وَيَظْلِمُهُمْ أَئِمَّةُ الْكُفْرِ وَالضَّلالِ وَأَشْيَاعُهُمْ فَمَنْ وَالاهُمْ وَاتَّبَعَهُمْ وَصَدَّقَهُمْ فَهُوَ مِنِّي وَمَعِي وَسَيَلْقَانِي أَلا وَمَنْ ظَلَمَهُمْ وَكَذَّبَهُمْ فَلَيْسَ مِنِّي وَلا مَعِي وَأَنَا مِنْهُ بَرِيءٌ.
Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad and Muhammad ibn al-Husayn from Muhammad ibn Yahya from Talha ibn Zayd from abu ‘Abdallah who has said the following. “The Imams mentioned in the book of Allah, the Most Holy, the Most High, are of two kinds. Allah, the Most Holy, the Most High has said, ‘We appointed them as leaders (Imams) to guide the people through Our command . .” (2:73) They do so but not because of the commads of the people. They allow our command to come first and before their own orders, and our laws before their own laws and judgment. “We made them the kinds of leaders (Imams) who would invite people to the fire . .” (28:4) ‘They let their own commands to come before the commands of Allah and their laws before the laws of Allah. They follow their desires against what the book of Allah, the Most Holy, the Most High requires.’”
مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَمُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ طَلْحَةَ بْنِ زَيْدٍ عَنْ أَبِي عَبْدِ الله قَالَ قَالَ إِنَّ الائِمَّةَ فِي كِتَابِ الله عَزَّ وَجَلَّ إِمَامَانِ قَالَ الله تَبَارَكَ وَتَعَالَى وَجَعَلْناهُمْ أَئِمَّةً يَهْدُونَ بِأَمْرِنا لا بِأَمْرِ النَّاسِ يُقَدِّمُونَ أَمْرَ الله قَبْلَ أَمْرِهِمْ وَحُكْمَ الله قَبْلَ حُكْمِهِمْ قَالَ وَجَعَلْناهُمْ أَئِمَّةً يَدْعُونَ إِلَى النَّارِ يُقَدِّمُونَ أَمْرَهُمْ قَبْلَ أَمْرِ الله وَحُكْمَهُمْ قَبْلَ حُكْمِ الله وَيَأْخُذُونَ بِأَهْوَائِهِمْ خِلافَ مَا فِي كِتَابِ الله عَزَّ وَجَلَّ.
