Assalamu Alaykum brothers/sisters:

Here are some verses from the Holy Quran concerning true and pure Imams:

إِنَّمَا يرِيدُ اللَّهُ لِيذْهِبَ عَنْكُمُ الرِّجْسَ أَهْلَ الْبَيتِ وَيطَهِّرَكُمْ تَطْهِيرًا(الأحزاب/33)

It is Allah's wish to remove all blemish from you, O Ahlul-Bayt, and purify you with a perfect purification. (33:33)

قُلْ لَا أَسْأَلُكُمْ عَلَيهِ أَجْرًا إِلَّا الْمَوَدَّةَ فِي الْقُرْبَى وَمَنْ يقْتَرِفْ حَسَنَةً نَزِدْ لَهُ فِيهَا حُسْنًا إِنَّ اللَّهَ غَفُورٌ شَكُورٌ(شوري/23)

Say, I ask no reward from you for it except the love of my kinsfolk. And whosoever does a good deed we add unto it a greater good for him. Lo, Allah is Forgiving, Responsive. (42:23)

فَمَنْ حَاجَّكَ فِيهِ مِنْ بَعْدِ مَا جَاءَكَ مِنَ الْعِلْمِ فَقُلْ تَعَالَوْا نَدْعُ أَبْنَاءَنَا وَأَبْنَاءَكُمْ وَنِسَاءَنَا وَنِسَاءَكُمْ وَأَنْفُسَنَا وَأَنْفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَلْ لَعْنَتَ اللَّهِ عَلَى الْكَاذِبِينَ(آل عمران/61)

And whoever disputes with thee concerning him after the inspired knowledge which has been given unto thee, tell him, "Come, let us call our sons and your sons; our women and your women; and ourselves and yourselves; then let us pray and invoke Allah's curse upon those who lie." (3:61)

وَاعْتَصِمُوا بِحَبْلِ اللَّهِ جَمِيعًا وَلَا تَفَرَّقُوا

Hold fast to the Rope of Allah, all of you together and do not diverge. (3:103)

يا أَيهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَكُونُوا مَعَ الصَّادِقِينَ(التوبة/119)

Be careful of your duty to Allah and be with the Truthful. (9:119)

وَأَنَّ هَذَا صِرَاطِي مُسْتَقِيمًا فَاتَّبِعُوهُ وَلَا تَتَّبِعُوا السُّبُلَ فَتَفَرَّقَ بِكُمْ عَنْ سَبِيلِهِ ذَلِكُمْ وَصَّاكُمْ بِهِ لَعَلَّكُمْ تَتَّقُونَ(الأنعام/153)

Lo, this is My Straight Path, so follow it and do not follow other ways or else you will diverge from His way. (6:153)

يا أَيهَا الَّذِينَ آمَنُوا أَطِيعُوا اللَّهَ وَأَطِيعُوا الرَّسُولَ وَأُولِي الْأَمْرِ مِنْكُمْ)

O you believe, obey Allah and obey His Messenger and those amongst you who are give supreme authority (by Allah). (4:59)

وَمَنْ يشَاقِقِ الرَّسُولَ مِنْ بَعْدِ مَا تَبَينَ لَهُ الْهُدَى وَيتَّبِعْ غَيرَ سَبِيلِ الْمُؤْمِنِينَ نُوَلِّهِ مَا تَوَلَّى وَنُصْلِهِ جَهَنَّمَ وَسَاءَتْ مَصِيرًا(النساء/115)

Whoever opposes the Prophet after the guidance has been made manifest unto him and follows any path other than the path of the true believers, We will turn him towards that unto which he himself has turned, and We will expose him to Hell and a bad journey it will be. (4:115)

وَيقُولُ الَّذِينَ كَفَرُوا لَوْلَا أُنْزِلَ عَلَيهِ آيةٌ مِنْ رَبِّهِ إِنَّمَا أَنْتَ مُنْذِرٌ وَلِكُلِّ قَوْمٍ هَادٍ(الرعد/7)

(O Prophet) Lo! thou art a warner and for every community there is a guide. (13:7)

اهْدِنَا الصِّرَاطَ الْمُسْتَقِيمَ(الفاتحة/6)

صِرَاطَ الَّذِينَ أَنْعَمْتَ عَلَيهِمْ غَيرِ الْمَغْضُوبِ عَلَيهِمْ وَلَا الضَّالِّينَ(الفاتحة/7)

Guide us in the Straight Path: The Path of those whom Thou hast blessed... (1:6-7)

وَمَنْ يطِعِ اللَّهَ وَالرَّسُولَ فَأُولَئِكَ مَعَ الَّذِينَ أَنْعَمَ اللَّهُ عَلَيهِمْ مِنَ النَّبِيينَ وَالصِّدِّيقِينَ وَالشُّهَدَاءِ وَالصَّالِحِينَ وَحَسُنَ أُولَئِكَ رَفِيقًا(النساء/69)

They are those whom Allah has blessed among the prophets and the verifiers, the martyrs and the righteous. (4:69)

لَا يسْبِقُونَهُ بِالْقَوْلِ وَهُمْ بِأَمْرِهِ يعْمَلُونَ(الأنبياء/27)

يعْلَمُ مَا بَينَ أَيدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يشْفَعُونَ إِلَّا لِمَنِ ارْتَضَى وَهُمْ مِنْ خَشْيتِهِ مُشْفِقُونَ(الأنبياء/28)

They (i.e., prophets and Imams) do not say anything until He orders, and they act (in all things) by His command. He knows what is before them and what is behind them and they (i.e., those saints) offer no intercession except for anyone whom Allah accepts, and they are in awe and reverence of His (glory). (21:27-28)

إِنَّمَا وَلِيكُمُ اللَّهُ وَرَسُولُهُ وَالَّذِينَ آمَنُوا الَّذِينَ يقِيمُونَ الصَّلَاةَ وَيؤْتُونَ الزَّكَاةَ وَهُمْ رَاكِعُونَ(المائدة/55)

Verily your master is only Allah, and His messenger and those among the believers who establish worship and pay the poor due while they are bowing down in prayer. (5:55)

وَإِنِّي لَغَفَّارٌ لِمَنْ تَابَ وَآمَنَ وَعَمِلَ صَالِحًا ثُمَّ اهْتَدَى(طه/82)

And lo! Verily I am the Most forgiving towards him who repents and believes and does good and then follows the guidance. (20:82)

يا أَيهَا الَّذِينَ آمَنُوا ادْخُلُوا فِي السِّلْمِ كَافَّةً وَلَا تَتَّبِعُوا خُطُوَاتِ الشَّيطَانِ إِنَّهُ لَكُمْ عَدُوٌّ مُبِينٌ(البقرة/208)

O you who believe, enter into peace, all of you, and do not follow the footsteps of the Satan. (2:208)

ثُمَّ لَتُسْأَلُنَّ يوْمَئِذٍ عَنِ النَّعِيمِ(التکاثر/8)

Then, on that day, you will be asked concerning the blessing. (102:8)

يا أَيهَا الرَّسُولُ بَلِّغْ مَا أُنْزِلَ إِلَيكَ مِنْ رَبِّكَ وَإِنْ لَمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ وَاللَّهُ يعْصِمُكَ مِنَ النَّاسِ إِنَّ اللَّهَ لَا يهْدِي الْقَوْمَ الْكَافِرِينَ(المائدة/67)

O you Messenger, convey what has been revealed unto you by your Lord, for if you do not do so, you will not have conveyed His message at all. And Allah will protect you from the people. Lo! Allah guides not the disbelieving folk (5:67)

الْيوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا فَمَنِ اضْطُرَّ فِي مَخْمَصَةٍ غَيرَ مُتَجَانِفٍ لِإِثْمٍ فَإِنَّ اللَّهَ غَفُورٌ رَحِيمٌ(المائدة/3)

This day have We perfected for you your religion and finalized Our blessing upon you, and We are pleased that Islam be your religion. (5:3)

َأَلَ سَائِلٌ بِعَذَابٍ وَاقِعٍ(المعارج/1)

لِلْكَافِرِينَ لَيسَ لَهُ دَافِعٌ(المعارج/2)

A questioner asked for the inevitable punishment to befall the disbelievers which no one can avert. (70:1-2)

وَإِذْ أَخَذَ رَبُّكَ مِنْ بَنِي آدَمَ مِنْ ظُهُورِهِمْ ذُرِّيتَهُمْ وَأَشْهَدَهُمْ عَلَى أَنْفُسِهِمْ أَلَسْتُ بِرَبِّكُمْ قَالُوا بَلَى شَهِدْنَا أَنْ تَقُولُوا يوْمَ الْقِيامَةِ إِنَّا كُنَّا عَنْ هَذَا غَافِلِينَ(الأعراف/172)

And when your Lord brought forth from the lions of the Children of Adam their seed, and made them bear testimony about their souls (He asked):"Am I not your Lord?" They said: "Yes, we bear witness." (7:172)

أَمْ يحْسُدُونَ النَّاسَ عَلَى مَا آتَاهُمُ اللَّهُ مِنْ فَضْلِهِ فَقَدْ آتَينَا آلَ إِبْرَاهِيمَ الْكِتَابَ وَالْحِكْمَةَ وَآتَينَاهُمْ مُلْكًا عَظِيمًا(النساء/54)

Or are they jealous of those men because of that which Allah has bestowed upon them in His bounty? (4:54)

لَا يمَسُّهُ إِلَّا الْمُطَهَّرُونَ(الواقعة/79)

None touches (the depth of meaning of Quran) save the purified ones. (56:79)

هُوَ الَّذِي أَنْزَلَ عَلَيكَ الْكِتَابَ مِنْهُ آياتٌ مُحْكَمَاتٌ هُنَّ أُمُّ الْكِتَابِ وَأُخَرُ مُتَشَابِهَاتٌ فَأَمَّا الَّذِينَ فِي قُلُوبِهِمْ زَيغٌ فَيتَّبِعُونَ مَا تَشَابَهَ مِنْهُ ابْتِغَاءَ الْفِتْنَةِ وَابْتِغَاءَ تَأْوِيلِهِ وَمَا يعْلَمُ تَأْوِيلَهُ إِلَّا اللَّهُ وَالرَّاسِخُونَ فِي الْعِلْمِ يقُولُونَ آمَنَّا بِهِ كُلٌّ مِنْ عِنْدِ رَبِّنَا وَمَا يذَّكَّرُ إِلَّا أُولُو الْأَلْبَابِ(

No one knows its interpretation except Allah and those who are firmly ground in knowledge. (3:7)

وَمَا أَرْسَلْنَا قَبْلَكَ إِلَّا رِجَالًا نُوحِي إِلَيهِمْ فَاسْأَلُوا أَهْلَ الذِّكْرِ إِنْ كُنْتُمْ لَا تَعْلَمُونَ(الأنبياء/7)

وَمَا أَرْسَلْنَا مِنْ قَبْلِكَ إِلَّا رِجَالًا نُوحِي إِلَيهِمْ فَاسْأَلُوا أَهْلَ الذِّكْرِ إِنْ كُنْتُمْ لَا تَعْلَمُونَ(النحل/43)

Ask the people of Reminder if you do not know. (21:7, 16:43)
