Another letter to him from him (the imam) also

17. Muhammad Bin Yahya, from Muhammad Bin Al-Husayn, from Muhammad Bin Ismail Bin Yazi’e, from his uncle Hamza Bin Yazi’e who said: ‘Abu Ja’far عليه الصلاة والسلام wrote to Sa’d Al-Khayr: - ‘In the Name of Allah عز وجل, the Beneficent, the Merciful. Having said that, your letter came to me عليه الصلاة والسلام in which you have asked how much it is necessary to learn and the obedience to the one عليه الصلاة والسلام whose pleasure is the Pleasure of Allah عز وجل. So then you had said to yourself, then you will not be blamed if you then avoid some other. You are (also) amazed (by the fact) that the Pleasure of Allah عز وجل, and obedience to Him عز وجل, and His عز وجل Advice is neither accepted, nor found, nor recognised except within the servants who are unrecognised (unknown to public), who are alone (away) from the people. The people have taken them in ridicule and they ascribe to them evil matters to the extent that it was said that one cannot be a Believer and is not a Believer until he becomes more hated by the people than the carcass of a donkey. And if you suffer from the affliction similar to what we عليه الصلاة والسلام have suffered, so do not consider the strife of the people (against you) like a Punishment of Allah عز وجل, and I عليه الصلاة والسلام seek Refuge with Allah عز وجل as well as for you all from that, to Bring near your destination which though is a far distance. And know, may Allah عز وجل have Mercy upon you, that one cannot achieve the Love of Allah عز وجل except by hatred from a lot of the people, nor His عز وجل Wilayah except by being their enemy, and losing (their friendship) is very little in comparison to that which is Gained from Allah عز وجل, for a people who know. O my عليه الصلاة والسلام brother, verily Allah عز وجل Mighty and Majestic has Made regarding everyone from the Messengers عليه السلام a successor عليه السلام who remains, from the people of the knowledge, calling the one who has strayed towards the guidance, and observes patience along with them upon the suffering, answering to the Call of Allah عز وجل and calling towards Allah عز وجل. So look at them عليه الصلاة والسلام, may Allah عز وجل have Mercy upon you, for they عليه الصلاة والسلام are in a high position even though they would be in affliction in the world and considered to be menial. They عليه الصلاة والسلام revive the dead by the Book of Allah عز وجل, and they عليه الصلاة والسلام visualise by the Light of Allah عز وجل from the blindness. How many who had been killed by the Iblees (la) were revived by them عليه الصلاة والسلام, and how many lost and strayed ones were guided by them عليه الصلاة والسلام, sacrificing their عليه الصلاة والسلام blood to save the servants from destruction, and how good are their عليه الصلاة والسلام effects upon the servants, and how ugly are the effects of the people against them عليه الصلاة والسلام’.
