12 A1-Amin promises in his document the following: I have contracted with God's servant Harun, with full approval and with good will on my part, to comply with all that he has conveyed to my brother ʿAbd Allah in the matter of the succession, the caliphate, and all the affairs of the Muslims after me, surrendering that to him, and what he has appointed for him in the viceregency of Khurasan and all its dependencies, and the estates assigned him by the Commander of the Faithful, or given him from his own lands or exchanged with him in estates and assignments; all that he has given him in his own right by way of wealth, ornaments, jewels, furnishings, garments, residences or animals, whether small or great; all these shall be for ʿAbd Allah, the son of Harun, Commander of the Faithful, conveyed to him without restriction, and I have recognized this item by item. In the event of the Commander of the Faithful's death, and the passing of the caliphate to Muhammad his son, Muhammad must carry out all that Harun, Commander of the Faithful, has provided for in the governing of Khurasan and its marches by ʿAbd Allah. It is not for Muhammad, son of the Commander of the Faithful, to turn any officer or soldier or any other man assigned to ʿAbd Allah by the Commander of the Faithful away from him, nor to turn ʿAbd Allah, son of the Commander of the Faithful, away from any part of the governorship given him by his father, nor to summon him therefrom to himself, nor to separate any one of his followers and officers from him or any of his officials and functionaries, any merchant or any accountant or any collector, and not to cause any harm to befall him in any matter small or great, nor to come between him and the discharge of his functions there with his own opinion or disposition, nor to occasion to anyone of those assigned to ʿAbd Allah by his father from the people of his family, his followers, his judges, his officials and secretaries, his officers, retainers, mawlas. and army, anything that might cause harm to them or constraint, whether to their persons, their families, or their dependents, nor to anyone coming from them on an errand, nor yet to shed their blood or touch their possessions, their estates, their houses, their allotments, their goods, their slaves, their animals, or anything of theirs small or great, or any of the people by his order, advice, or caprice, or by his permission or instigation thereto to any one of the children of Adam, nor to give orders about their affairs; he or any of his judges or officials, except by the permission of ʿAbd Allah son of the Commander of the Faithful, and his opinion and the opinion of ʿAbd Allah's qadis. ḏabari, , Tārīkh, 3:655–58;Google ScholarJohn, A.
