Hadith 1: 

Prophet Mohammad (صلى الله عليه وآله) and the Imam's (عليله السلام) see the actions:

عن يعقوب بن شعيب قال: سألت أبا عبدالله (عليه السلام) عن قول الله عزوجل: " اعملوا فسيرى الله عملكم ورسوله والمؤمنون " قال: هم الائمة

I asked Aba Abd-Allah Imam Sadiq (عليه السلام) about the words of Allah (عز وجل), "Act. so Allah will see your work and (so will) His Messenger and the believers" (8:105). 

Imam (عليه السلام) said, "They (the believers) are the Imams."

Hadith 3:

حَدَّثَنَا الْهَيْثَمُ النَّهْدِيُّ عَنْ إِسْمَاعِيلَ بْنِ مِهْرَانَ قَالَ‌ كُنْتُ أَنَا وَ أَحْمَدُ بْنُ نَصْرٍ عِنْدَ الرِّضَا (ع) فَجَرَى ذِكْرُ الْإِمَامِ فَقَالَ الرِّضَا (ع) إِنَّمَا هُوَ مِثْلُ الْقَمَرِ يَدُورُ فِي كُلِّ مَكَانٍ أَوْ يراه [تَرَاهُ مِنْ كُلِّ مَكَانٍ‌

It has been narrated to us by Al-Haysam Al-Nahdy, from Ismail Bin Mahraan who said, "I, and Ahmad Bin Nasr were in the presence of al-Rida (عليه السلام). The mention of the Imam (as) ensued. 

Imam al-Rida (عليه السلام) said, "Indeed the Imam is like the full moor circling in every place", or He sees from every place."

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ عَلِيِّ بْنِ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ قَالَ‌ كُنْتُ أَنَا وَ صَفْوَانُ عِنْدَ أَبِي الْحَسَنِ (ع) فَذَكَرُوا الْإِمَامَ وَ فَضْلَهُ قَالَ إِنَّمَا مَنْزِلَةُ الْإِمَامِ فِي الْأَرْضِ بِمَنْزِلَةِ الْقَمَرِ فِي السَّمَاءِ وَ فِي مَوْضِعِهِ هُوَ مُطَّلِعٌ عَلَى جَمِيعِ الْأَشْيَاءِ كُلِّهَا.

From Ahmad b. Muhammad who said: " I was with Safwan in the presence of Imam al-Rida (عليه السلام) and they mentioned the Imam and his virtue.

Imam al-Rida (عليه السلام) said, "The position of the Imam on the earth is like the position of the moon in the sky, He while in His place is aware of all the things, all of it."

Hadith 4:

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيِّ بْنِ النُّعْمَانِ عَنْ أَبِيهِ قَالَ حَدَّثَنِي الشَّامِيُّ عَنْ أَبِي دَاوُدَ السَّبِيعِيِّ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ عَنْ رُمَيْلَةَ قَالَ‌ وُعِكْتُ وَعَكاً شَدِيداً فِي زَمَانِ‌ أَمِيرِ الْمُؤْمِنِينَ(ع)فَوَجَدْتُ مِنْ نَفْسِي خِفَّةً فِي يَوْمِ الْجُمُعَةِ وَ قُلْتُ لَا أَعْرِفُ شَيْئاً أَفْضَلَ مِنْ أَنْ أُفِيضَ عَلَى نَفْسِي مِنَ الْمَاءِ وَ أُصَلِّيَ خَلْفَ أَمِيرِ الْمُؤْمِنِينَ(ع)فَفَعَلْتُ ثُمَّ جِئْتُ إِلَى الْمَسْجِدِ فَلَمَّا صَعِدَ أَمِيرُ الْمُؤْمِنِينَ(ع)الْمِنْبَرَ عَادَ عَلَيَّ ذَلِكَ الْوَعْكُ فَلَمَّا انْصَرَفَ أَمِيرُ الْمُؤْمِنِينَ(ع)وَ دَخَلَ الْقَصْرَ دَخَلْتُ مَعَهُ فَقَالَ يَا رُمَيْلَةُ رَأَيْتُكَ وَ أَنْتَ مُتَشَبِّكٌ بَعْضُكَ فِي بَعْضٍ فَقُلْتُ نَعَمْ وَ قَصَصْتُ عَلَيْهِ الْقِصَّةَ الَّتِي كُنْتُ فِيهَا وَ الَّذِي حَمَلَنِي عَلَى الرَّغْبَةِ فِي الصَّلَاةِ خَلْفَهُ فَقَالَ يَا رُمَيْلَةُ لَيْسَ مِنْ مُؤْمِنٍ يَمْرَضُ إِلَّا مَرِضْنَا بِمَرَضِهِ وَ لَا يَحْزُنُ إِلَّا حَزِنَّا بِحُزْنِهِ وَ لَا يَدْعُو إِلَّا أَمَّنَّا لِدُعَائِهِ وَ لَا يَسْكُتُ إِلَّا دَعَوْنَا لَهُ فَقُلْتُ لَهُ يَا أَمِيرَ الْمُؤْمِنِينَ جَعَلَنِي اللَّهُ فِدَاكَ هَذَا لِمَنْ مَعَكَ فِي الْقَصْرِ أَ رَأَيْتَ مَنْ كَانَ فِي أَطْرَافِ الْأَرْضِ قَالَ يَا رُمَيْلَةُ لَيْسَ يَغِيبُ عَنَّا مُؤْمِنٌ فِي شَرْقِ الْأَرْضِ وَ لَا فِي غَرْبِهَا.

Narrated from Rumaylah who said,

"I became extremely ill during the time of Amir al-Momineen (عليه السلام). I found in myself lightness (felt better) on Friday, and I said to myself, I don’t know of anything which is better than pouring water on myself  and Praying behind Amir al-Momineen (عليه السلام).

I did that, then went to the Mosque. When Amir al-Momineen (عليه السلام) ascended the Pulpit, that illness of mine returned. When Amir al-Momineen (عليه السلام) left and entered the palace, I entered along with Him. 

The Imam (عليه السلام) said, " Rumaylah, I ( saw that you were covering parts of your body with other parts (due to illness)".

I (Rumaylah) said, "Yes, and I related to Him what had happened with me and made me to come and Pray behind Him."

The Imam (عليه السلام) said, "O Rumaylah, there is none from the believers who falls sick except that We get sick with his illness, and he does not grieve except that We are aggrieved by his grief, and he does not supplicate but that We say Ameen to his supplication, and he does not become silent except that We supplicate for him".

I (Rumaylah) said, "O Amir al-Momineen (عليه السلام), may Allah (عز وجل) make me to be sacrificed for You, this is for those who are with You in the palace? Have you see those who were in the far corners of the earth?" 

The Imam (عليه السلام) said,, "O Rumayla, no believer is absent/hidden from Us in the east or the west of the earth."

Narrated that Abu Baseer said:

"I entered the Mosque along with Aba Jafar Imam Baqir (عليه السلام) while the people were entering and leaving the Mosque.

Imam (عليه السلام) said to me, "Ask the people if they see Me." 

Abu Baseer said, "Everyone whom I met, I asked him, "Do you see Aba Jafar (عليه السلام)? - they said, "No" while Abu Jafar (عليه السلام) was standing there. 

Then Abu Haroon al-Makfoof entered and Imam (عليه السلام) told me, "Ask him." 

So I said to him, "Do you see Aba Jafar (عليه السلام)?, He said, "Is he not standing?". 

I asked him, "How did you know this?", He said, "How shall I not know, while He is a shining light (noor).

Abu Baseer said, I heard the Imam (عليه السلام) saying about a man from Africa - How is the situation of Rashid? 

Abu Haroon al-Makfoof said, "He was alive and well when I left him and he gives Salam to You." 

Imam (عليه السلام) said, "May Allah (عز وجل) have mercy upon him". 

He said, "He died?". 

Imam (عليه السلام) said, "Yes". 

He said, "When?"

Imam (عليه السلام) said, "2 days after you left."

He said, "By Allah (عز وجل), He was not ill and there was no reason for this."

Imam (عليه السلام) said, "Who ever dies, dies due to an illness or a reason."

Abu Baseer said, "Who is that man?"

Imam (عليه السلام) said, "He was a man who befriended Us and Loved Us." 

Then the Imam (عليه السلام) said, "Do you think that Our seeing eyes or hearing ears are not along with you! Verily evil is what you think. By Allah (عز وجل), nothing from your actions is hidden from Us. So present yourselves to Us with beauty and make yourselves used to doing good and be from among the people who do good and are known by it, as this is what I command My children and followers (shia).:

Hadith 6:

أَبِي رَحِمَهُ اَللَّهُ قَالَ حَدَّثَنِي عَبْدُ اَللَّهِ بْنُ جَعْفَرٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ اِبْنِ أَبِي نَجْرَانَ قَالَ سَمِعْتُ أَبَا اَلْحَسَنِ ع يَقُولُ مَنْ عَادَى شِيعَتَنَا فَقَدْ عَادَانَا وَ مَنْ وَالاَهُمْ فَقَدْ وَالاَنَا لِأَنَّهُمْ مِنَّا خُلِقُوا مِنْ طِينَتِنَا مَنْ أَحَبَّهُمْ فَهُوَ مِنَّا وَ مَنْ‌ أَبْغَضَهُمْ فَلَيْسَ مِنَّا شِيعَتُنَا يَنْظُرُونَ بِنُورِ اَللَّهِ وَ يَتَقَلَّبُونَ فِي رَحْمَةِ اَللَّهِ وَ يَفُوزُونَ بِكَرَامَةِ اَللَّهِ مَا مِنْ أَحَدٍ مِنْ شِيعَتِنَا يَمْرَضُ إِلاَّ مَرِضْنَا لِمَرَضِهِ وَ لاَ اِغْتَمَّ إِلاَّ اِغْتَمَمْنَا لِغَمِّهِ وَ لاَ يَفْرَحُ إِلاَّ فَرِحْنَا لِفَرَحِهِ وَ لاَ يَغِيبُ عَنَّا أَحَدٌ مِنْ شِيعَتِنَا أَيْنَ كَانَ فِي شَرْقِ اَلْأَرْضِ أَوْ غَرْبِهَا وَ مَنْ تَرَكَ مِنْ شِيعَتِنَا دَيْناً فَهُوَ عَلَيْنَا وَ مَنْ تَرَكَ مِنْهُمْ مَالاً فَهُوَ لِوَرَثَتِهِ شِيعَتُنَا اَلَّذِينَ يُقِيمُونَ اَلصَّلاََةَ وَ يُؤْتُونَ اَلزَّكََاةَ وَ يَحُجُّونَ اَلْبَيْتَ اَلْحَرَامَ وَ يَصُومُونَ‌ شَهْرَ رَمَضَانَ وَ يُوَالُونَ أَهْلَ اَلْبَيْتِ وَ يَتَبَرَّءُونَ مِنْ أَعْدَائِهِمْ‌[مِنْ أَعْدَائِنَا] أُولَئِكَ أَهْلُ اَلْإِيمَانِ وَ اَلتُّقَى وَ أَهْلُ اَلْوَرَعِ وَ اَلتَّقْوَى وَ مَنْ رَدَّ عَلَيْهِمْ فَقَدْ رَدَّ عَلَى اَللَّهِ وَ مَنْ طَعَنَ عَلَيْهِمْ فَقَدْ طَعَنَ عَلَى اَللَّهِ لِأَنَّهُمْ عِبَادُ اَللَّهِ حَقّاً وَ أَوْلِيَاؤُهُ صِدْقاً وَ اَللَّهِ إِنَّ أَحَدَهُمْ لَيَشْفَعُ فِي مِثْلِ رَبِيعَةَ وَ مُضَرَ فَيُشَفِّعُهُ اَللَّهُ تَعَالَى فِيهِمْ لِكَرَامَتِهِ عَلَى اَللَّهِ عَزَّ وَ جَلَّ.

Narrated through a chain of trustworthy narrators that Abu al-Hasan al-Rida (عليه السلام) said,

"Whoever has enemity with Our Shia, has surely has enmity with Us, and whoever has befriended them has befriended Us, because they (i.e. the Shia) are from Us created from Our clay. Whoever loves them is from Us, and whoever hates them is not from Us. Our Shia see through the light (noor) of Allah, and they live in the mercy of Allah, and they are successful by the honor of Allah. 

There is not one of Our Shia who becomes ill except that We become ill with his illness, and he does not grieve except that We grieve with his grief, and he does not become happy except that We become happy with his happiness, and no one of our Shia is absent/hidden from Us wherever he is, in the east or the west of the earth. 

And whoever from Our Shia leaves a debt - it is upon Us, and whoever from them leaves any money - it is for his heirs. 

Our Shia are those who establish prayer (salat), give zakat, perform pilgrimage to the Holy House, fast the month of Ramadan, follow/befriend the AhlulBayt (عليه السلام), and disassociate themselves from Our enemies. Those are the people of faith and piety, the people of abstaining from the world (wara) and piety. 

And whoever rejects them has rejected Allah, and whoever slanders/defames them has slandered Allah, because they are truly the servants of God and His sincere friends. By Allah, one of them may intercede (do shifat) for the as many people as in the tribes of of Rabiah and Mudar, and Allah (تعالى) will accept their intercession due to His honor."
