Please state the long list of advice provided by the Prophet S.A.W.S. to Maa'dh R.A. on his departure to Yemen.

1. Mu'aadh ibn Jabal (Radhiallaahu Anhu) says that when Rasulullah (Sallallaahu Alayhi Wasallam) sent him (as a governor) to the Yemen. He said, 'Beware of living in comfort and luxury, for the pious bondsmen of Allah do not live in comfort and luxury.' (Fadhaail-e-Sadaqaat pg.527) 2. When sending Mu'aadh ibn Jabal (Radhiallaahu Anhu) to Yemen as a governor, Rasulullah (Sallallaahu Alayhi Wasallam) advised him to command people to observe Salaat and to pay Zakaat, and then said, 'When they pay Zakaat, avoid taking the best of their property; and protect yourself against the curse of an oppressed person, for there is no barrier between Allah Ta'ala and the supplication of the oppressed.' (Fadhaail-e-Sadaqaat pg.298)
3. When Allah's Messenger (Sallallaahu Alayhi Wasallam) sent him to the Yemen, he went out with him giving him advice, Mu'adh (Radhiallaahu Anhu) riding and Allah's Messenger (Sallallaahu Alayhi Wasallam) walking beside his riding beast.
Then when he finished he said, "Perhaps, Mu'adh, you may not meet me after this year, but perhaps, you may pass this mosque of mine and my grave." Mu'adh wept from grief over the departure of Allah's Messenger (Sallallaahu Alayhi Wasallam).
The Prophet (Sallallaahu Alayhi Wasallam) then turned facing Medina and said, "Those nearest to me are the pious, whoever they are and whenever they are." (Mishkaat)
4. Allah's Apostle (Sallallaahu Alayhi Wasallam) said to Mu'adh when he sent him to Yemen, "You will go to the people of the scripture. So when you reach there, invite them to testify that none has the right to be worshipped but Allah, and that Muhammad is His Apostle (Sallallaahu Alayhi Wasallam). And if they obey you in that, tell them that Allah has enjoined on them five prayers in each day and night. And if they obey you in that tell them that Allah has made it obligatory on them to pay the Zakat which will be taken from the rich among them and given to the poor among them.
If they obey you in that, then avoid taking the best of their possessions, and be afraid of the curse of an oppressed person because there is no screen between his invocation and Allah."
5. Allah's Messenger (Sallallaahu Alayhi Wasallam) sent AbuMusa and Mu'adh ibn Jabal (Radhiallaahu Anhuma) to Yemen. He sent each of them to administer a province as Yemen consisted of two provinces.
The Prophet (Sallallaahu Alayhi Wasallam) said (to them), "Facilitate things for the people and do not make things difficult for them (Be kind and lenient both of you with the people, and do not be hard on them). Give the people good tidings and do not repulse them."
So each of them went to carry out his job. When either of them toured his province and happened to come near (the border of the province of) his companion, he would visit him and greet him.
Once Mu'adh toured that part of his state which was near (the border of the province of) his companion, AbuMusa. Mu'adh came riding his mule till he reached AbuMusa and saw him sitting, and the people had gathered around him.

Behold! There was a man tied with his hands behind his neck. Mu'adh said to AbuMusa, "O Abdullah ibn Qays! What is this?" AbuMusa replied. "This man has reverted to Heathenism (kufr) after embracing Islam." Mu'adh said, "I will not dismount till he is killed." AbuMusa replied, "He has been brought for this purpose, so get down." Mu'adh said, "I will not dismount till he is killed." So AbuMusa ordered that he be killed, and he was killed.
Then Mu'adh dismounted and said, "O Abdullah (ibn Qays)! How do you recite the Qur'an?" AbuMusa said, "I recite the Qur'an regularly at intervals and piecemeal. How do you recite it, Mu'adh?"
Mu'adh said, "I sleep in the first part of the night and then get up after having slept for the time devoted for my sleep and then recite as much as Allah has written for me. So I seek Allah's reward for my sleep as well as my prayer (at night)."
6. When the Prophet (Sallallaahu Alayhi Wasallam) sent him (Mu'aadh) to the Yemen, he ordered him to take a male or a female calf a year old for every thirty cattle and a cow in its third year for every forty, and one dinar for every adult (unbeliever as a poll-tax) or cloths of equivalent value manufactured in the Yemen.
7. When the Apostle of Allah (Sallallaahu Alayhi Wasallam) sent him (Mu' aadh) to the Yemen, he said (to him): Collect corn from the corn, sheep from the sheep, camel from the camels, and cow from the cows. (Abu Dawud) 8. When the Prophet (Sallallaahu Alayhi Wasallam) sent him (Mu'aadh) to the Yemen, he ordered to take from everyone who had reached puberty one dinar or its equivalent in Mu'afiri garment of Yemen origin. (Abu Dawud) 9. Some companions of Mu'adh ibn Jabal said: When the Apostle of Allah (Sallallaahu Alayhi Wasallam) intended to send Mu'adh ibn Jabal to the Yemen, he asked: How will you judge when the occasion of deciding a case arises?
He replied: I shall judge in accordance with Allah's Book. He asked: (What will you do) if you do not find any guidance in Allah's Book? He replied: (I shall act) in accordance with the Sunnah of the Apostle of Allah (Sallallaahu Alayhi Wasallam).
He asked: (What will you do) if you do not find any guidance in the Sunnah of the Apostle of Allah (Sallallaahu Alayhi Wasallam) and in Allah's Book? He replied: I shall do my best to form an opinion and I shall spare no effort.
The Apostle of Allah (Sallallaahu Alayhi Wasallam) then patted him on the breast and said: Praise be to Allah Who has helped the messenger of the Apostle of Allah to find something which pleases the Apostle of Allah. (Abu Dawud)
10. Allah's Messenger (Sallallaahu Alayhi Wasallam) sent me (Mu'aadh) to the Yemen, but when I set off he sent after me and I was brought back. He then said, "Do you know why I sent for you? Do not take anything without my permission, for it is unfaithful dealing, and he who acts unfaithfully will come on the Day of Resurrection with the unfaithful deeds he has done. This is why I called you. Now go off to your task." (Mishkaat) 11. When Allah's Messenger (Sallallaahu Alayhi Wasallam) sent him (Mu'aadh) to the Yemen, he said, "Beware of living sumptuously, for Allah's servants do not live sumptuously." (Mishkaat)
